Following what I perceive to be the recommended backup strategy, we have our Kerio Connect OS on one volume, the mail store on another volume, and a separate backup volume for Connect's internal backup to use. I make offsite backups of the OS and Backup volumes to tape, leaving the primary mail store alone. The backup schedule available in Connect seems to be designed around weekly full backups and additional incrementals (daily or whatever). We used to back up to tapes which were taken offsite. We are changing to cloud backups for offsite, and I'm noticing that the biggest time and space utilizer is the email backups. With full weekly backups into new zip files, we are pushing a couple hundred GB of new zip files into the cloud every week, and that's a lot. The mail store itself changes very little, other than new emails coming in and occasional folder reorganizing it's mostly static, so my question is this:
Why shouldn't we back up the live mail store instead of the backup zip files? Obviously there is the individual file change here or there that would be missed at/during the backup, but the hundreds of small files changing each day would be much easier to update to a cloud type of backup set than hundreds of GB of zip files. What do we put at risk by leaving the Kerio Connect backups for a local drive failure type of recovery and backing up the live mail store instead?
I was going to ask support directly but figured it would be a worthwhile topic for public discussion, I'm sure we aren't the only ones going through this transition.
