Backup Exec 10D Rev 5629 Linux differential using modified time backups up All data

Hello, I have been trying to resolve an issue with backing up Linux servers using modified time. I use BackupExec 10.1D Rev5629. We run a "Full - Back up files - Using modified time". Then the first "Differential - Back up changed files since last full - Using modified time" backups all the data again as if it were a full. I made the selection list first and then made the jobs using the same list. According to Veritas this is supposed to work but even after making these jobs several times and reisntalling the agents i still can't get it to work. This is a tuff one and i am hoping someone has had a similar issue and knows the fix. Of course our support contract has expired which is why i am using this forum. Thanx for any help you may have Jim

Are there any events in the event viewer relatiing to this please?  If so can you post them, so we can assist you more
Can you expand on "doesnt work", could mean a lot, are there any errors, what is the backup doing etc?
Is the backup exec installed on linux or windows please?

No events pertaining to the fact that the differential backup job is backing up all of my 1.7Tbs of  Linux data. Just events listing the Backup exec database was backed up. This is running on a windows2003 server. Basically on saturday I run a linux backup of 1.7Tb. then on monday i run a differential backup of the same selection list and it backs up 1.7Tb which fails because i only have 1Tb allocated to differentials.

ok so after installing 4 different agents and making test backup jobs i finally figured out what the problem was. Our backup set is so large that we often get errors backing up files. So the job would fail on any error. If the job does not complete succesfully without and errors the Differebtial job will in turn do a FULL backup. hopefully this will save others the pain that i went through. Windows backup jobs do not exhibit this behavior.
