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 ?
