Years ago, we first switched from a tape only backup solution to a disk & tape solution using Microsoft's DPM. A few years later, we moved backup's of our virtual environment to Veeam B&R, but kept DPM for physical servers. VB&R does a nightly backup of all virtual servers, but we wanted more frequent backups of some data within those VM's, so DPM kept backing up file shares, exchange, sql db's, etc from those servers. DPM also backed everything up to tape once a week, including the latest .vbk file from VB&R.
Now that VB&R has added support for Tape, and for backing up physical machines, I'm wondering if VB&R is ready to be our sole backup platform, eliminating DPM. My primary concern at this point is whether VB&R can come close to the backup structure that we have with DPM. Take the backups of SQL databases for example. DPM is configured to Synchronize the DB every 15 minutes. Then, 3 times per day, it performs an 'Express Full Backup'. If we ever have a failure that requires restoring the DB from backup, we always have a backup available that is current to within 15 minutes. If the database were damaged somehow before the last 15 minute sync ran and we need to go back further, we can then go back to the last express full backup. (We can't restore to any given 15 minute point in time sync, only the most recent.)
We use similar settings for backing up our Exchange and Sharepoint environments. For file shares, those also synchronize every 15 minutes, but a recovery point is created every 4 hours.
I'm sure that VB&R can do better for us than just a once daily backup of all VM's, but can it give us frequent backups of critical data stores like this, without having to back up our entire environment as often?
