One of our sys. admins is looking for "snapshot" capable
utility/software for Linux other then Veritas.  Hardware/OS:  Compaq
Proliant running Redhat 7.x (oracle rdbms)

I strongly recommend xv:

http://rpmfind.net/linux/RPM/solaris/RPMS/i386/xv-3.10a-13.i386.html

It does other things (resizing, thumbnails ..) well and makes
snapshots of the windows or whole screen well.

Here is a copy of xv manual:

Thank you for your response.  By "snap shot" we meant data not screen.
 Does the utility you describe offer this type of back-end, backup
software-like functionality?

Thank you.

Ooops,
            xv is a graphics utility.

  For backup software consider

KDat (licence: GPL)
KDat is a tar-based tape archiver ..
 A snapshot file is used to determine which files have changed since
the last
   incremental backup. Only the files that have changed will be
archived.

If you want to use snapshots (speaking about storage snapshots,
not screen snapshots) in Linux, but don't like the idea of 
using VxFS/Veritas, you have two options

a) LVM Snapshots
http://www.tldp.org/HOWTO/LVM-HOWTO/x136.html
"A wonderful facility provided by LVM is 'snapshots'. This allows
the administrator to create a new block device which is an exact 
copy of a logical volume, frozen at some point in time. Typically 
this would be used when some batch processing, a backup for instance, 
needs to be performed on the logical volume, but you don't want to 
halt a live system that is changing the data. When the snapshot 
device has been finished with the system administrator can just 
remove the device. This facility does require that the snapshot 
be made at a time when the data on the logical volume is in a 
consistent state, later sections of this document give some 
examples of this. "


b) NetApp Filer
http://www.netapp.com/
High performance NFS serer. You can mount resources that are shared
by NetApp on your Linux box and use all the nice Netapp's features, 
including snapshots.
