If I want to run Kerio differential backups aggressively (This is from an SSD we're planning on purchasing so it shouldn't affect performance significantly I hope), is a full backup every weekend followed by differentials every 2 hours too much? That is to say, do differential backups get wonky if you have 72 of them in between full backups?
The reason I want to do this is that TRIM commands don't work with SSD RAID. My boot drive would be a RAID 1 HDD mirror (this would also be where the archive and backups are stored) and only the live mailstore would live on a single 960GB SSD. I wouldn't want to lose more than 2 hours of data in case things went downhill.

The problem running this level of differential backup's is that every two hours, user's will be locked out of mailboxes as it goes through to scan for any changes and then back this up to the files.
Its always best to run diff's outside of normal business hours to reduce the chance of intrusion on users. It would also depend on how much data is detected as changed and require storing in the backup.
You could also rely on the Archive feature as well as this would be saving any inbound and outbound mail messages as well.
I hope this helps.
