Backup Linux

Nobody's Hero — Tue, 08 Jul 2003 11:02:27 GMT

Can I get some feedback on what types of backup software people are using in the Linux world besides a tar ball. We are just entering onto the Linux platform and are not sure what our backup strategy should be.

Does Arcserve have a Linux client?

Give a look at the 'dump' command.

Also, the 'amanda' package lets you to
setup a master backup server for a local network.
It is part of the RedHat distribution.

My favourite is Mondo, as it allows you to burn CD also, even through network...

Arcserve does exist for Linux, but you have to pay for it, as for Windows...

Assuming you're backing up to anotner Linux/Unix machine use dump package which contains both dump and restore commands.

Hi,

Omniback has clients for backing up Linux on Intel based machines. We've been doing it for a long time. If you have Linux on other types of systems that Omniback can't talk to [mainframes, etc.], you can NFS mount the filesystems to a box that does have an Omniback client and get them backed up that way.

Check out Arkeia (http://www.arkeia.com).
I've used it for 5 years at home as my backup tool and also used it 'commercially' in my last job.
There is a 30-day demo of the Professional version available for download. There is also a free version available, see http://www.arkeia.com/arkeialight.html

The FAQ is here http://www.arkeia.com/arkeiafaq.html

The only thing I would point out is that if you have a lot (more than 100000) of files to backup, I would put the Arkeia 'database' on a separate disk.

HTH,
Michael.

Hello!

Use dump/restore tools, using fast backup tape like LTO or DLT.

Also you have omniback client for backup via
network on HPUX.

I am told by documentation that amanda is a backup system that works pretty well to tape.

I like the omniback idea, but can it restore the grub partition.

As far as data goes a cheap way to go is this:

A cron script swaps out the /etc/exports file with a different one that exports:

/ ro

read only.

Then it does exportfs -a(maybe not -a I forget)

On an HP-UX server say 10 minutes later(make sure the clocks are synched).

mount nfs linuxbox:/

Now fbackup can back up the entire Linux system.

There is an obvious security flaw there, and nfs needs to be patched up tight on both boxes. My solution has the advantage of costing nothing. Omniback is costly. fbackup is extremely reliable.

Also: I back up boot configuration as follows:

Boot to Windows 98 diskette(network enabled for Intel, otherwise attach a cdwr)
Norton Ghost

It takes very good disk images and is good for disaster recovery purposes.

We use Mondo for all production Linux Servers.
We will use the bootable backup functionality.

I may put a omniback client on these boxes soon, just for the case of an Enterprise Management for "normal" backup and restore.

I will always keep Mondo around for the same reasons we will always do Ignite backups on HP-UX.

If only one-button DR was as stable as Mondo and Ignite!

Hello!

You can use mindi and mondo that is like
ignite on the hpux (made backup and also restore).
