[Veritas-bu] Backing up unformatted primary partitions
Hi all, I have the pleasure of trying to protect data for a system that writes (obviously in a proprietary manner) data to an unformatted partition in Windows. I've read the guides, and see that it's unsupported by NBU (I tried anyways, it teases you by actually backing up the blocks, then fails with a status code 1). Just curious, has anyone out there tried to do this without the use of hardware snapshots (which I think I'll have to fall back on)? Cheers, Jon La version française suit le texte anglais.

Re: [Veritas-bu] Backing up unformatted primary partitions
If I had to do this in UNIX/Linux and couldn't do it with NBU I'd probably use the dd command. On doing a quick check I do see there are dd commands for Windows. The first link I found is: http://www.chrysocome.net/dd Essentially what you do is dd the device so you get all its blocks into a dump file. You can then backup that dump file. Not sure who well the above works for Windows - just throwing it out there as something to explore. If you have snapshotting capabilities that already work for this purpse its probably better to go that route but I'm not sure from the way you described it that you'd be able to backup the snapshot any better than the original. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Jonathan Dyck Sent: Thursday, April 08, 2010 9:20 AM To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Subject: [Veritas-bu] Backing up unformatted primary partitions Hi all, I have the pleasure of trying to protect data for a system that writes (obviously in a proprietary manner) data to an unformatted partition in Windows.

Re: [Veritas-bu] Backing up unformatted primary partitions
Thanks for the idea, looks brilliant (if I can get it to work ;-) I definitely have concerns with the snapshots, mostly because they'll be copy-on-write snaps, not clones, and they'll reside on the same storage array as the primary data (obviously not ideal, as if the array goes, so too do the snapshots). I'll let you know how it goes.

Re: [Veritas-bu] Backing up unformatted primary partitions
Just one more info about DD, you will need an area of at least the same time of the original area to store the dump because DD dumps the whole partition, not only the written area ...

Re: [Veritas-bu] Backing up unformatted primary partitions
Absolutely. They wanted to sell us a 15-20k piece of add-on software that archives data from the unformatted into normally readable content on another LUN.

With the sticking accelerator issue a Corolla might go as fast as a Ferrari eventually. ;-) Of course you haven't said what your disk storage is - mentioning LUN makes me think it is an external storage array. Some of those have ways to copy data between arrays so if you have more than one array of the same manufacture you might look into that as a possibility.

Re: [Veritas-bu] Backing up unformatted primary partitions
Quick check, you said you tried backing this up already - do you mean as a raw partition ? i.e. File list looked something like: \\.\E: If that's not working for you then I agree with Jeff, the best you could hope for would be removing the single point of failure by using a clone of some kind. If that does work.then you'll need to quiescence that volume somehow (backup mode, shutdown the app, whatever) before the backup, or go with a clone of the LUN and then back up the clone as a raw partition.

Re: [Veritas-bu] Backing up unformatted primary partitions
Exactly, did the \\.\E file:///\\.\E : backup, results in a failure (status code 1), but it chugs through all the contents OK until the end. Here's some info for those interested... dd for Windows seems to have the same issue, it chugs through, creating an image of the unpartitioned drive, but then spits out an error at the end Error reading file: 87 the parameter is incorrect. dd.exe if=\\.\z: of=f:\my_backup.img bs=1M But, it reports the same number of records in and out, and leaves behind the disk image on disk, which is promising. So to test a recovery, I format the drive (Z:\ in this case), write some dummy data onto it, and then attempt the recovery: dd.exe if=f:\my_backup.img of=\\.\z: bs=1M Which progresses for an appropriate amount of time (similar to the backup process), and doesn't spit out error at the end, and my drive shows up as unpartitioned again. It also reports the same number of records in and out as the backup, so I'm optimistic it works. I think I'm going to actually go ahead and test this when the techs show up to install it. So yes, this is all on external SAN storage, so my backup plan will be to replicate the primary volume across to my other site, and take daily snapshots of that replicated LUN. Not my favourite thing to do, but will do the trick and probably satisfy my business unit. Cheers.

They wanted to sell us a 15-20k piece of add-on software that archives data from the unformatted into normally readable content on another LUN. We're trying to figure out if we can avoid that, as we don't have any archival requirements for this data, so it'd be one of those buying a Ferrari when you need Corolla kind of deals. -Original Message- From: Nardello, John [mailto:john.narde...@cgi.com] Sent: April 8, 2010 11:49 AM To: Jonathan Dyck Cc: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Subject: RE: [Veritas-bu] Backing up unformatted primary partitions Just to ask the obvious question - how does the vendor expect you to perform backups of their proprietary system ? Do they have any recommendations that might help ? - John Nardello Your backups are only as good as your restores. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Jonathan Dyck Sent: Thursday, April 08, 2010 6:20 AM To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Subject: [Veritas-bu] Backing up unformatted primary partitions Hi all, I have the pleasure of trying to protect data for a system that writes (obviously in a proprietary manner) data to an unformatted partition in Windows. I've read the guides, and see that it's unsupported by NBU (I tried anyways, it teases you by actually backing up the blocks, then fails with a status code 1). Just curious, has anyone out there tried to do this without the use of hardware snapshots (which I think I'll have to fall back on)? Cheers, Jon La version française suit le texte anglais
