So the question becomes "When is the incremental backup marked inactive?" Does it even make sense for an incremental to have a different retention to a full?
When the next full is done. No it does not make sense to be different. For example My full backups will expire x days after the next full backups is started. All of the incrementals that depends on the previous full expires x day after the next full have completed. At the time the next full completes, all of the previous incremental backups are mark inactive. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of Steven Harris Sent: Thursday, June 26, 2014 10:31 PM To: ADSM-L@VM.MARIST.EDU Subject: Exchange Incremental Expiry Hi Again Further to my last, the customer for which I am designing exchange backups has until now been a Domino shop. Previously we have taken a Weekly selective/daily incremental for the databases (remembering that an incremental on Domino only backs up new databases and those that aren't logged) plus daily or more frequent log backups. The database management class keeps for 18 months. The logs are kept for 100 days. I'm now supposed to implement this in Exchange. I can do a weekly full/daily incremental with no problem and put them to different management classes as I do for Domino, however the TDP for Exchange manual states Incremental object names are always unique. These names contain qualifiers whose values make them unique. Incremental object names are generated at the time of the backup and therefore are not predictable and cannot be specified. So the question becomes "When is the incremental backup marked inactive?" Does it even make sense for an incremental to have a different retention to a full? IIRC the same applies with MSSQL and the client deletes the logs when the full on which they depend is no longer on the server. If that is the case for exchange then there is no point in a different retention for incrementals. Please chime in if you know Thanks Steve. Steven Harris TSM Admin Canberra Australia.
