We have about 3tb on Celerra and backed up using CIFS shared out to two
windows servers and have each unix host backing up their own NFS. Slower
than I would like, but does give granularity to restore which was a
must.  I also did not want to dedicate a tape drive.

Subject: EMC CELERRA backup options - need feedback

I am looking for information/guidance/suggestions/sanity-checks on my
current project involving backing up an EMC CELERRA NAS.

Originally, I was told to approach this as an NDMP backup.  The more we
look at the drawbacks/limitation of TSM NDMP backups vs what we need to
be able to do with the backups, we are looking at alternative methods
for backups.

Our scenario for the NAS is going to be like this:
1. 300GB to start - up to 3TB.
2. Multiple different clients, both real servers (Windows and *NIX) and
"virtual server" connections 3. Lots of workstations connecting to the
NAS via AD group policies/"virtual server mountpoints" to redirect their
"My Documents" to the NAS.

We need granularity of control over who can restore what from the TSM
backups. The NDMP method doesn't seem to be able to handle this.
We need to perform offsite backup copies (i.e. DR, audit requirements)
which the NDMP method makes painful (snapshots......backing up twice).

So, how do you backup your CELERRA ?
