[AccessD] Linux file server backup

Gustav,

Do you use this?  Can you comment on actual performance, speed and usage?
Does the system maintain a bunch of file fragments that it reconstructs in
the event a restore is needed?  Or does it magically "fix up" the target
backup file so that it is a single file that can then be transferred back if
needed?

Have you ever tested the restore?

Hi all

For those interested in Rsync for Windows, check out DeltaCopy (free):

Hi Jim

Are you talking about a Linux file server with "built-in" backup service or
is this a separate box you set up for backing up an existing file server?
Does Ubuntu have some special tools for easy setup of RAID arrays that other
distributions miss? 

It sounds like the first, but then you only have a backup of the disks -
leaving a critical single point of failure: the controller.
While some say "controllers don't fail", they do, though rarely. We have
seen two.

We are currently testing a setup where we use Rsync for backup. It's very
basic but it allows backup to remote servers. Probably not a solution for
TB-sized backup but most clients are well below this.

Well John; 

The RAID drives are mostly duplication... just add a couple or 320GB, single
partition drives ($200.00) and you could have a mirrored backup. Fast,
reliable and (in context) cheap... who says you can't have it all

I have done this using an Ubuntu Linux. It uses a real old box (1.5 years
old with four older small 100GB drives), the install was easier than
Windows, (and when I say it is easy it really is. The only prompts that
require entry are how much space to allocate for the partition(s) and an
admin password.), it took only 15 minutes to connect to the network (which
has always been the biggest pain when managing mix systems). The resultant
partition created was across the all the drives making 400GBs of space. It
is real cheap and fast. 

I have been selling this backup concept to clients who want a reliable cheap
backup and have made a few sales. Even one government office is seriously
planning on contracting my services.

Jim
