Backup Exec 2010 and Linux Debian

[gbacca]

Hi,

I recently installed backup exec 2010 to backup a file server that is a linux Debian.
The problem I have is ALL my differentials and incrementals backups are working as FULL backups, instead of differentials or incrementals.

So, I did some test:

TEST1
1. I do a full backup using the modification time.
2. After a while, I do a modification in a file, and then I do a differential backup using the modification time.

Result: both backups are FULL backup

TEST2
1. I do a full backup using the option "copy all files" (or similar: my interface is in spanish language).
2. After a while, I do a modification in a file, and then I do a differential backup using the modification time.

Result: both backups are FULL backup

So, how can I fix this problem: I'am unable to do incremental or differential backup in my linux.

Thank you!

I forgot to say that I had to active the parameter "noatime" in the partitions of my linux (but all the tests were done after that activation).
Here I attach an snapshot after executing the command "mount".
