This has been bugging me for a while, and not matter how much doco I read there's no black and white explanation of archived (stubbed) email vs standard protection (backup) retention. Obviosly the whole idea of Onepass is to roll the whole thing into one seamless operation, but this does make the prospect of things being deleted before they should be an issue.
My understanding is as follows:
- Standard mailbox backup retention is still controlled via the storage policy, with normal aging taking place acording the the copies retention.
- The "Basic Retention Rules for Data/Compliance Archiver data" option in the SP copy has no impact on OnePass operations, this only relates to legacy archiving.
- Unless the "honour storage policy retention" option is set to 1, archive retention is set at the subclient level through Retention --> Media Pruning.
What confuses me is this; Under Retention --> Media Pruning on the OnePass mailbox iDA subclient it states: "During Synthetic Full, prune items from the archive" and gives a default of 1825 days, or the option of Never. On the FS version of OnePass archiving it mentions "If deleted on source", but here it simply gives an amount of time to keep it, regardless of the stubs state in the mailbox.
Does this mean that if this is set to 1825, and a user tries to recall that archived stub 2000 days since archiving took place they will be out of luck? I've been setting this to 'Never' to be sure, but it seems weird that and archiving solution would swap out an object to save space, and then remove the item that the stub points to at a later date.
If anyone has a simple way of explaining this it would be awesome, ideally I would loike the solution to keep standard backups for the time specifed in the various copies of the SP, and keep archived email for as long as there is a stub referencing it.
