Hi Skylar, Allan,

Skylar - would I be right in thinking that you have 130 million files on your 
Isilon or did you mean you have 130 million files across all versions? May I 
also ask how many directories and user accounts are involved?

Allan - would you be happy to give some idea of the size of your Isilon setup? 
We're being asked about backing it up to tape now and have a number of concerns.

Cheers,
Steve

Our current state (in implementation now) is:

+ Default, short-term backup needs addressed by snapshots.

+ Disaster-recovery needs addressed by replication

+ Longer-term backup needs addressed by incrementals to TSM, with
retention set to keep "enough" data.  e.g.

"Monthlies for 2 years"

verexists: 26
verdeleted: 26
retextra: 800
retonly: 800

and do incrementals monthly.
