Differential/Incremental backup not working properly
I'm using BE 2010 R2 and got the following issue.
I make B2D full backup(reset archive bit)(Overwrite only), and then immediately try to make a differential/incremental backup.
The same backup list for both full and incr/diff is used; otherwise different media sets for both backups are used(configurated to unlimited append).
The dif/inc backup(7 servers, 97 GB), following by full backup start to fill space up to insane 140+ GB (I stopped the process, cause it was way too long)
I tried various configs of dif/inc backups(archive bit/time of modification) and etc.
To my mind If I made full backup, then immediately made incremental then it's gonna be like some kilobytes. Obviously something is wrong with my configuration. How do I make dif/inc backups work properly?
Thanks in advance!
