Windows Server Backup in scheduled to do daily System State backups on each server in our solution.
Sometimes instead of incremental backups (150MB), it performs full backups (12GB+).
It seems that this decision is internal to the windows tool, and it is not transparent, when it is going to do this.
So far, it has happened on 2 of 16 servers, around September 10th and then October 11th (about a month apart).
Trying to unerstand the reasons why and when it is doing this...
Any clues what to look for? There did not seem to be any amnual maintenance on these servers, and not all of them had this sudden jump in backup traffic.
