It splits files into blocks (defaulting to 32KB, but that's configurable), computes hashes (two separate hashes per block) and stores them in a file in the backup config directory. These are used to detect modified blocks. It also computes a hash of an entire file and stores it in the same hash file.
This has been a popular feature request when it has come up in the veeam forums and you will also find lots of talk there about the use of rsync.I have been preforming two separate backups for some time with veeam as i want to replicate offsite and backup to local disk.Besidesd two separate job schedules (ie one runs at 12:00 and the other at 12:15) You can chain the two jobs together within veeam so that when one job is finished the next kicks off. To do this look at the job summary of the second job and it gives you a command line argument to kick off the job. Then you go to the first job and and from job settings select advanced and add it to the post job activity. (note this is from veeam 6.0)Only problem is when the first job fails and if you have automatic retry enabled you end up with both jobs trying to run at the same time.
That means I wont be able to schedule two backups pointing to same destination share, one for database one for full image.About rentention Windows message is clear that it would only keep one backup on share, which is fine with me that I don't to define storage limit. But it does not show anything about running two backup on same server at different hours at night.Or may be I am better off with complete backup instead of database level backup. I was using VDP for application level backup but that was unreliable when I did the test restore. I have failures on VDP for image level backup, which I might be able to fix it after reboot, as I got the feeling that Windows VSS and VDP agent is getting into issue.Worst case I will setup database backup on Windows and Image level backup from VDP appliance for Vmware.
