Hey All,

Using Backup Exec 11D, I have a client where the backup for previous day is 285GB and then next day 281GB and apart from a reboot nothing has changed I am advised.

Is there an ability to compare backup sets to see what is new and not missing between sets either with BKUPEXEC or another util please.

Windows 2003 SP2 Backup Exec 11D (tape backups).

Many thanks in advance

I am not familiar with a tool to compare two backups within Backup Exec, however if the backup job for the server does the entire server, including system state, then the variable size will be due to temporary files that were cleaned upon restart.  In example some anti-virus keep ongoing logs for each boot, if it has been months since the last reboot these logs can get quite large.  Symantec Anti-virus is one of the AV softwares that will create this symptom.

If the backup include "everything" on the C: drive, then your Paging file is probably being backed up also.  If this is variable size and your system has a lot of memory, that would also help account for the size difference after the reboot.
