Title: Retrospect revisited
Post by: DigiCorn on January 10, 2012, 09:37:09 AM
Last Friday my AIT tape drive refused to eject a tape. I disassembled the machine yesterday only to find that the tape had physically snapped. There's 300+ jobs archived on that tape and no redundant backup. I think I can get it repaired and the data saved from a repair facility, but now my Retrospect library is not going to have proper reference as the data will be archived to a new tape.

Looks like I finally forced the boss' hand and he agreed that today we're going to go to Fry's and build a new backup system. The plan is to buy the latest version of Retrospect, several 2TB externals and a new blu-ray burner supported by Retrospect. I will then have to copy the contents of all 28 of our AITs to the externals and rearchive with Retrospect to blu-ray. Then, burn a second copy to store off site and possibly a third copy to store in the safe here. The system will then backup all data nightly to one of the externals, and we will swap externals every few days or weekly, storing one off site so the worst we will do is lose a week's worth of work should something go wrong.

Is there a better way to do this, or do I have it pretty dialed in?

I'm a cheap bastard and am not a fan of Retrospect. I'd get at least 2 external drives, use Karen's powertools to backup (full then incrementals) and rotate the drives out weekly. The optical backup is up to you, I don't trust them.

Ditto.

Or you can use Time Machine or CCC on a Mac or Windows backup, all FREE, on a PC which works great. I've never been a fan of Retrospect.

be careful, some older versions of Retrospect don't play well with the newer versions.
I had a tape drive die that we used Vers 4 of Retrospect on (Mac OS9).
I didn't want to restore all the jobs on the tapes so I thought I could import the old library and then have it on the new version.

but...My newer version (v6) doesn't recognize the older version library.
I had to repair the drive. Cost us about $300 US.

Well aware of this david, which is why my plan is to restore all AIT to externals HDs and write to blu-ray via Retrospect. My plan hopes to accomplish three things:

1 - gets rid of AIT tape (we'll put this and the old Retrospect server with the tape drive in storage)
2 - creates a less expensive redundant backup (a few $$$ for blu-ray vs. $40+ for AIT tape)
3 - new Restrospect creates a new archive library of the new blu-rays and not the old AIT tapes, so old library files are not needed

My old archive library file is f**ked anyway because with losing this tape, even if/when I recover it, it will need to be rearchived and the archive library will think it still exists on the old tape

I use CCC on all my Macs.

For cataloging I use a freebie app that came with my install of Toast. It works, but usually I just search using the Mac's Finder.

sounds like a lot of work.
If your library is anything close to mine, it would not be as easy. I have approx 1000 ait tapes (maybe more, I've never counted them). My robotic carousel holds about 90 tapes in it.
We have ours set to do Incrementals 4 times a day as well as archive once a month. So, if one of my archive tapes goes south, I still have the files on Incremental.

Post by: DigiCorn on January 10, 2012, 12:35:09 PM
We don't have an X-Serve; we have a Windows 2003 server, so while the Mac advice is nice, all my files are stored on a RAID array.

We have 28 AIT tapes, and when I first started our original file server took a shit and I had to build a new one. When I redid the system, I had to re-library the tapes. It took about 4 days. I guarantee it will take longer than that to extract them and rearchive. We've slowed down a bit; it will get me hours.

Post by: Farabomb on January 10, 2012, 12:53:39 PM
I don't understand, if you backup to HDDs why the need for retrospect? I can understand if you still want a optical backup (I'd just use HDDs and rotate, again) but if you have decent directory structure on the externals it should be easy to find what you need. Removes the need to spend the time creating a new library in retrospect, restore everything to the drives and back them up.
Title: Re: Retrospect revisited
Post by: DigiCorn on January 10, 2012, 12:58:15 PM
Would like to have a "permanent" backup in place. We pull from archives all the time. All the data on those tapes would fill those HDs. We've had one RAID 5 array and 2 external HDs fail in the past few years. There's no way I am going to trust an external HD to hold all my data. As far as backups go, we will run nightly backups to the HDs, but for permanent archiving we will have the old AIT tapes in storage, a set of blu-rays also offsite and a set of blu-rays onsite.

This is why I like forums. Each person has their own preferences from their experiences. I have HDDs over 10 years old that are still working fine. Wouldn't trust them for storage but they still work.

I'd like to know how a RAID 5 array failed? They are made to be redundant (it's in their name) so you can recover from failures. If more than one drive failed a once I'd consider it a fluke... or karma. :tongue:

If you want a "permanent" backup double the amount of externals. If it spans more than one external label them job#0-1200 alpha and the next job#1200-5000 alpha and so on. Restore all the libraries, name the next set of drives job#0-1200 beta and dupe them. Set your backup software of your choice (free or cheap) to run incrementals on Friday and rotate them out weekly. You will have a backup onsite, one at best a week behind offsite and when you are not backing up or pulling from backup, shut the externals off. Do a full backup monthly to stave off bit rot and you should be good.

My active directory took a beating and died when we had five power outages in one day.
The raid survived, but we had to do a lot of re-directing to be able just to navigate to the raids once we found out the problem. Took almost a full day to get it back online. The AD is still dead.

anything can happen.

Here's the fruits of our current "solution" to date. Yup, scores & scores of CDs!!! All done through some outdated version of Retrospect. Oh, and they were created on a few different CD burners, so when you go to retrieve a job, it's a crapshoot whether you've got the CD in the right burner to read it or not. Good times.

I can't tell you how often I've wanted to squirt an entire bottle of Zippo™ fluid on that 4-drawer cabinet, flick a match & just sit back and watch it burn. Burn motherfucker BURN.  :dev2:

I feel your pain. CDs! Not even DVDs.    :sad:  Well, we're getting a new RAID5 server upstairs in the office, and pp will be archiving jobs to there. Any natives I'll ZIP fonts folders.
Theoretically, bye-bye DVD burning. Feel slightly uneasy about it though. Irrationally, I think. Our IT support, (as used by head office) is not cheap, but they seem pretty good.

I've always been curious how hot it gets inside a "fireproof" cabinet. Hot enough to warp plastic? That would wreck havoc on tapes or optical storage.

Again, I still stand by HDDs for long term storage. As long as you treat them properly they will outlast optical.
Title: Re: Retrospect revisited
Post by: DigiCorn on January 11, 2012, 09:15:22 AM
In all my years, I have yet to have an optical disk (other than a Zip or Jazz) go bad on me. In that same time, I've had a number of HDs crap out. My belief is that optical disks are cheap, and portable, so burning redundant copies is the way to go for me. The other thing to look at here is that some of this data to be archived is so old, or been replaced/updated with newer art and will never be used again. The problem is, there's no way of knowing which files those are... and too many to go through and weed out. I don't want to write data like that to an HD that's basically just sitting there and taking up space. If it's on a blu-ray then I have it if I ever need it for something and if I don't need it it's not using up space that could be used for something else.
Title: Re: Retrospect revisited
Post by: Farabomb on January 11, 2012, 09:54:08 AM
In all my years I've had many optical disks go bad. Mishandle them and scratch the top surface and it's toast, scratch the bottom and maybe you can polish it back onto working. They are made cheaply and I've seen them delaminate in a climate controlled room. Keep a HDD in a not well ventilated enclosure or even case and watch it die. Turn it on only when needed and keep it cool and happy and it will live a long life. Drop it while it's off and it will probably survive. Hell, get a HDD dock and use internal drives and swap the out when full. Better option than external drives becasue you won't forget to shut it off. Pull the drive and park it on a shelf.

Iirc Zip and Jazz were magnetic, not optical.

I just realized something. We have a "fire-proofed" server room - special doors, walls, etc. None of our back-ups are stored in there, but what really concerns me is that I just noticed last week that it has that crappy tiled drop-ceiling & there's some kind of leak that developed above it & some of the tiles are discolored & sagging. If it's supposed to be an environmentally sealed room, a fire in the shop nearby could easily travel across the roof, set fire to that room's ceiling or collapse it, etc.

Some times the sheer ignorance in this place leaves me stunned.

If it was a 2TB SSD I'd probably feel safe with archiving permanently to that... but for long term, I still like going cheaper with blu-ray and burning redundant copies. In reality, they only have to last me a few years before the art gets updated and/or replaced and becomes obsolete. I rarely pull a job from more than 5 years ago.

I pull jobs from 10 to 15 years ago on occasion off CD or DVD. No problem at all. I don't have one single HD that has lasted more then 5 years. They all start clicking after awhile. SSD is something that is a pipe dream at this point. I would seriously consider switching, but only after the price comes WAY down.

I am really wary of Maxtor, Seagate and WD. I like the Hitachis. With the typhoon or whatever in Thailand, our local Fry's is jacking up the prices of HDs while optical media prices are dropping. They also only sell one HD to a customer until the shortage ends.

Blu-ray isn't cheaper. A 10 pack of 50 gb TDK disks is $78 (no name disks can be found cheaper). I can buy a 500 gb hard drive for $50.

I just bought 8, 1Tb drives for 48 bucks each.

I saw those prices before the Thailand floods but everything I see now is higher than that. Where did you get those from?

Are those 25 gb or 50 gb? The cheapest no-name I found with a guick search was $45 for the 50 gb disks.

I can send you a maxtor that's 10 years old, shit I have a pair of them. Used them on many gaming machine builds in a RAID array system drive. I liked small, fast drives for the boot/system drives and they work to this day. Haven't had issue with any major manufacturer except IBM and their "deathstar" 120g drives. They got out of the game and sold that division to.... Hitachi. For that reason and that reason only I will avoid buying any Hitachi drives. WD and Seagate are my main 2 and since prices are so low I don't have to consider maxtors mainly becasue of others hatred of them.

I will say again, treat them well and HDDs last. I have 3 that were under water and now I might get a dock just to see if they still work.

Cheaping out on your optical media for backups is asking for trouble. They are cheap for a reason.

Agreed. You better do triple quadruple backups and you might end up with one you can read in 6 months.

Storage Format: Hard Disk Drives

Pros: Large storage capacity for the price / Typically good lifespan

Cons: Susceptible to malfunction due to mechanical failures and physical impact

If you own a computer, be it desktop or laptop, then you most likely have files stored on a hard drive of some type, probably housed within your computer. While may be the safest place to store your hard drive(s,) doing so will not guarantee a trouble free experience. Why? A hard drive is somewhat similar to an old vinyl record player: housed inside the hard drives' outer casing are discs which spin as a mechanical arm moves back and forth above the disc surface, reading and writing data to and from the platters beneath. While this method of data storage has worked for many, many years, there has always been one unavoidable fault which leads to inevitable failure of a hard drive: the aforementioned mechanical parts. As with any device which relies on constant and precise mechanical movement to run, hard drive parts eventually fail, usually taking your data to the grave with them. Due to the precision with which they operate, hard impacts may also cause a hard drive to read or write data in error, and possibly fail altogether as well. Despite these shortcomings, most hard drives have a life expectancy of at least 3-5 years, with many reportedly living a healthy life at 10+ years of age.

Storage Format: Optical Media (CD-R / DVD-R)

Pros: Inexpensive, portable

Cons: Inconsistent lifespan, temperamental storage requirements, data lost over time due to degradation

Optical media, such as burnable CD's and DVD's, are quite handy for short term storage of data. However, they remain a less than desirable choice for long term and mission critical data archival. The reason is simple: everyday optical media degrades quickly and easily. Although many manufacturers claim their optical media will last for 30 years or more under perfect conditions, their actual lifespan with normal use and storage is typically closer to a few years (at most) than a few decades. There are many different factors which conspire against the lifespan of CD-R's and DVD-R's; sub-par dyes (the reflective portion of a disc where data is written) which degrade much sooner than rated, exposure to heat, cold, or sunlight which also degrade said dyes, and weak or wrongly calibrated optical disc burners which fail to write data as intended. All of these factors make everyday optical media formats a less than favorable storage choice; ok for short term data storage, but definitely not the choice for long term backup of important information.

Behold...

For your hard drive worries, on the 11th of Jan 2012, ZFS for OS X finally has arrived...

http://www.tenscomplement.com (http://www.tenscomplement.com)

Don Brady, formerly of a twenty year tenure of software engineering at Apple, has started [http://tenscomplement.com/ a company] to provide a commercially supported version of the latest free ZFS for Mac OS.  The company's plans include an all-new native GUI for ZFS management. Ten's Complement describes itself as "an open source company" and is working closely with the Illumos community, while they decide how to handle the specific licensing terms of their impending code release. Don knows the architecture and implementation of behind-the-scenes Mac OS specifics which means that it will likely be a much better port ultimately than MacZFS. Don's work has repeatedly redefined Apple's storage strategy.  He was on the original HFS+ team in the 1990s, and later was one of two intrepid and visionary originators of the skunkworks port of ZFS to Mac OS.  His work is the spiritual successor of the MacZFS project, which may not otherwise exist as we know it.

This article (http://www.zdnet.com/blog/storage/why-raid-6-stops-working-in-2019/805) and the one mentioned within (http://www.zdnet.com/blog/storage/why-raid-5-stops-working-in-2009/162?tag=content;siu-container) are the best at explaining why we all need ZFS. In a nutshell, once you get over a terabyte in drive size, and that drive fails, the odds become very high that you will encounter an unrecoverable error in your backup drive while trying to restore your data.

Couple that with the fact that bits can get flipped when non ECC ram (http://en.wikipedia.org/wiki/ECC_memory) hiccups, or when the storage controller hiccups, you don't even know if your data really made it there safely to begin with. ECC = Error-correcting code. So what does that tell you about your non ECC ram? ZFS doesn't come into play at this stage, so you need ECC. ZFS does replace the storage controller woes. ZFS paired with ECC means when your data is written it is written verbatim. Otherwise, it's a maybe.

Then comes along bit rot, the magnetic substrate wears down over time and bits flip, like the cassette tape that doesn't sound the same after 100 plays. Or a cosmic ray zaps your only copy of some precious file. Even if you have a parity copy on RAID, what if the parity copy is the one that gets zapped, then your working drive fails and you replace it? Congratulations, you now have two zapped copies and you don't even know it (yet). ZFS records metadata (think checksum) that will know which one got zapped and replace the bad with the good when you resilver. Resilvering is the process in ZFS for resyncing your drives, a maintenance routine that can and should be run periodically whether scheduled or manually. This is supposed to be done with RAID as well, but it isn't smart enough to know which copy went bad so it really doesn't do you a whole lot of good.

All of this is why I have 750GB drives in the XRAID that our prepress department uses. The odds are in our favor that when I replace a drive it will resync before encountering an error on one of the other drives. But we do suffer bit rot on this system. I have seen it a few times now over the last five years. I go to move a file or grab a copy and it is garbled toast.

If you want to trust your data on your hard drives = ECC ram + ZFS.

If you want to trust your data on your opticals = M-Disc

Once your data is under wraps, you'll have time to investigate the Quantum Resonant Gyrator (http://pesn.com/2012/01/18/9602015_Quantum_Resonant_Gyrator_Embodies_Simple_Tesla_Technology/) with a COP of 600%! This means 6 times over unity! More advanced units have already achieved over 1000%.

I'm planning on making me some Tesla Tiki Torches for the back yard with this thing. Twenty bucks and a trip to Radio Shack, and you can transmit electricity wirelessly. And not just any old electricity, we're talking scalar cold electricity.

Spend eight minutes of your time, and you will walk away knowing that all we have been taught about physics is completely wrong!

So I gather ZEVO would be doing what ChronoSync does for me now, but more/better?

Yes and no. One of these is an application that syncs files, the other is a filesystem that syncs files.

Think FAT32, NTFS, HFS+, these are filesystems, so is ZFS. But unlike any other FS, it abstracts away and takes over other parts of the food chain (logical volume manager, RAID card, etc...), so it is not only the best FS, it is much more than that.

Employing it means you eliminate actual hardware pieces which reduces the number of physical components that will break. Even though it is used in enterprise settings for insanely high IOPS, the beauty is you can also take a bunch of cheap pure crap Maxtor drives through usb and still not lose data.

Since it's a LVM also, you can even mix and match firewire, usb, sata, thumb, flash, ooga boogas all in one volume.

It's also an open source non proprietary FS, so when your hardware fails, you can still read and write to it from some other hardware (OSX, FreeNAS, FreeBSD, Solaris, Ubuntu, etc...).

Your priorities are clearly out of order. If you rearranged just one of these it would make things much easier for you...

Fixed -> Stupid work, life, racing and Stupid girlfriend

She has a bit of geek in her (besides me) and loves playing video games so she's not all bad.

That's cool, as long as her console's in the kitchen.

She bought me my latest console and has no issue with me spending hours dicking around in Skyrim instead of paying all my attention to her.

The kitchen is real close to the living room but she's a much better baker than cook. I handle most of the cooking duties.
