Exchange online maintenance and Enterprise Vault

It all depends on a couple of things 1. What devices are you storing your vault store partitions? (SAN/NAS/NetApp) etc? 2. How much data are you currently backing up with Enterprise Vault? 3. What backup methods are you using? Regular tape backup? Flash backup? Snapshots etc? 4. What software are you using to perform the backups? 45 minutes is a rather short amount of time based on a fairly long archiving window and another thig to consider is that some backup software will not remove the archive bit from the DVS files on a differential or incremental backup Meaning that you would have pending items for up to a week until the full backups are performed You. Oils however use the Partition Secured Notification XML files that net backup or backup exec might generate or the trigger files as well
