Reply to: Backup strategy for small business

Yeah AIX has that too, but not sure you can boot from it.

The fundamental core of AIX has always been the BOS (Basic Operating System) all trimmed down with tiny partitions as it should be (root slice .5 gb etc) means the whole thing fits on a bootable DVD-RAM, everything else on separate VG's.

I've seen some sights on Linux (and Solaris to be fair), huge root slices, no way can you create bootable backups from that.

But maybe you can? You could from AIX NIM but obvs not from portable media.

You can image the disks using https://www.terabyteunlimited.com/image-for-linux.htm

That is about as bare metal as you can get, but you do have to take the server offline. Good enough for what I need, but obviously Mickey Mouse for Stek's needs.

LVM has a 'snapshot' feature. Not looked into it in any detail myself yet but have seen it being [mis-]used on a client project.

Trouble with Linux is is there a way of restoring to bare metal? I've not seen any other than kickstart rebuild, but would be interested if there are any (cheap/free) ones.

Planning this for current clientco though a huge multi - it's penny-pinch-tastic here!!

Decided to backup to local NAS, mkcd/mksysb for AIX BOS, savevg, rsync etc, savewpar (only place ever using Workload Partitions, save on PowerVM VET code cost) to said NAS, and then to cloud, not sure which yet, probably Dropbox but as corporate say we have to get rid of that - some other possibly Amazon thing.

That way I have bare metal restorable BOS from iso from mksysb, restorevg, rsync back, restorewpar, all within a few hours of powering up replacement box, not bad, lead time for replacement box is 3 weeks though so I don't know why I bother.

So trying to source a cheapo POWER6 or something to host somewhere in a DC or other site ATM.

The last one I done was for a small solicitors office. I installed a small NAS on site to store the backup and incrementals. for the off site full current copy I used a cloud based provider as others have suggested. In this case it was Carbonite. The on site setup used 2 x 3 PC licences of Acronis Truecopy. Job done, works well and the client was pleased at the simplicity. That environment was wintel based, I know that Acronis supports Linux but not sure to what extent

1 TB storage(Dropbox) with unlimited history(all file deltas) is probably less than 100 usd PER Year, I am sure there are other cloud providers that can get you sorted for a few hundred quid. Then any simple script will do, even manual once a week will also do, manual full BKP on Fridays and upload/sync to dropbox over the weekend, incrementals daily would be small so not a big deal to sync over night.

I know a number of companies who use Bacula at an enterprise level on Linux and have no complaints with it. You'll need to sit down and work out a proper backup and recovery strategy, i.e. how often a full and then do you do daily incrementals and so on. Not a light task even for an SME but something that has to be done and then...test, test and test again as you don't want to learn the hard way that the data can't be restored. Yes, you can backup to disk:

Bacula is a set of computer programs that permits the system administrator to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula can also run entirely upon a single computer and can backup to various types of media, including tape and disk.

I do have to admit that for the systems I provide to ISV's I just give them a large USB drive and some scripts which just copies their data although I do implement other more complex solutions when required.

Does it have to be tape/virtual tape ? Backula should be able to treat your USB drives as a local disk backup target, writing the backups straight to disk (into the disk file system).

This does not provide off-site backups, so if the whole office burned down, the backups might also be lost. To remedy that your friend could for example buy 7 disks, clearly label them and take them home, bringing only that day's disk into the office each day.

Would be ideal. I just couldn't find an example of how to get Bacula to do this. The forums seemed to indicate that vchanger was the way forward.

I think 2 disks, rotated would be ideal. Then when he isn't there to rotate, the current backup just gets overwritten.

I'll do some more reading.

Or additional/concurrent backups to cloud....

Anyway that's all good until the day it all goes wrong like when my previously perfect rsync solution at home lost the missus' Hamburg pics......

I never said it was.

Now, forget about Linux. Just advise how you would implement a tape backup strategy for an SME.

So far, it's working well. Active directory, KVM, email. All delivering many thousands of pounds worth of stable virtual infrastructure for nix.

Ive never been one to blame my tools mind

I've set up VTL's in AIX, but not that pile of poop Linux. In fact i've done the full TSM with storage pools etc but that costs money, still it's dream on AIX but a total fudge on Linux.

Hate these cheapo lash-ups, get them to do it properly!
