This keeps coming up. It's the hardest thing about TSM, to sell users on the way it works.
Tivoli's Storage Vision whitepaper has a comparison of the benefits you get by NOT using this Grandfather-father-son technique, but I wish somebody at Tivoli would come up with some better assistance to help us sell the incremental-forever -ooops, progressive backup methodolgy - to non-techie users. (Maybe it's there and I just don't know where to find it...?) I think Kelly Lipp has a good article on archiving and when it's sensible - maybe he'll post that link here again. Also, maybe some users have specific oddball scenarios they have run into that require surprising policy settings. It would be interesting to hear about those. Like, the user who goes on vacation for two weeks, and manages to trash here email file the day she leaves, doesn't notice it, Lotus touches the damaged file every day so it gets backed up again, and they don't keep 14 versions, so she gets back and the only good version (15 days old) has rolled off (expired). --------------------------------- Mr. Lindsay Morris CEO, Servergraph www.servergraph.com 859-253-8000 ofc 425-988-8478 fax > -----Original Message----- > From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED]]On Behalf Of > Marc Levitan > Sent: Thursday, April 04, 2002 8:51 AM > To: [EMAIL PROTECTED] > Subject: Monthly Backups, ...again! > > > A question was brought up while discussing retention policies. > > Currently we have the following retentions: > > Policy Policy Mgmt Copy Versions Versions Retain Retain > Domain Set Name Class Group Data Data Extra Only > Name Name Name Exists Deleted Versions Version > --------- --------- --------- --------- -------- -------- -------- ------- > COLD ACTIVE COLD STANDARD 2 1 5 30 > > NOVELL ACTIVE DIRMC STANDARD 30 1 120 365 > NOVELL ACTIVE STANDARD STANDARD 30 1 120 365 > > RECON ACTIVE DIRMC STANDARD 36 3 75 385 > RECON ACTIVE MC_RECON STANDARD 26 1 60 365 > > STANDARD ACTIVE DIRMC STANDARD 26 1 60 365 > STANDARD ACTIVE STANDARD STANDARD 26 1 60 365 > > > UNIX ACTIVE MC_UNIX STANDARD 30 1 60 30 > > > I believe that this provides for daily backups for over a month. > > There was a request to have the following: > 1) Daily backups for a week. > 2) Weekly backups for a month. > 3) Monthly backups for a year. > > I believe we are providing 1 & 2.
