Which one do you want?
. A backup solution that allows users to backup (could be files, could
be the whole system) onto a server that you own inside your organization, which
you will probably then backup to tape for offsite storage
. The users already sync their stuff onto a network fileshare inside
your organization, and now you want to backup your central NAS appliance to
another location offsite
. Nevermind any local NAS that may or may not already exist. Users
should backup directly to some external offsite system. (Which itself has ???
for backups)
For most situations, I would recommend either:
. Something like Ghost or True Image, which backs up the whole system,
at least once a month (but TI can do incrementals on a daily basis if you
want). Althesame, dailies can be larger than expected this way.
. Something like Rsync, or SyncToy, or Cobian Backup, which backs up a
specific folder or set of files to a central NAS. Your NAS has either VSS or
Snapshots enabled, so you don't worry about "A user deleted a file on their
computer, and then the sync happened, and then the file was also deleted from
the server."
. Guess what, True Image works for scenario 2 as well. You can have a
monthly full system image, and a daily incremental/differential system image,
and create a completely separate backup job that just does "My Documents" or
whatever. The only reason I'm not openly touting TI is because it's news to me
- never saw it till last week. It's $40 per license if you want it managed on
the local machine. It's $80 per license if you want a central management
console. It does everything under the sun, as far as I can tell. I only need
to see it action, put to the test more. Need to see it proven in real life.
Need to experience restoring a whole system up to yesterday. And then I'll
know if it's as good as it claims to be.
If you have something like a NetApp, or a ZFS server, you can do offsite
snapshots. Something like SnapMirror. This is totally ideal in a lot of ways.
If you have a Windows server, and another one offsite, you can make a VPN
between the two, and use DFS which is also ideal in a lot of ways.

Subject: [lopsa-tech] Small business backups over the internet
i'm used to doing backups internally, but i've recently been asked twice for
backup recommendations for small business setups with relatively small data
sets to backup. There are quite a few options out there, does any one have any
recommendation for this? Things i've played with previously were more geared
towards individuals than businesses.
Thanks!
