For Unix, it's by timestamp (mtime value on the inode).  If it's a
differential incremental, its all files changed since the previous full or
incremental backup of that same policy (mtime > last-backup-time) .  If it's
a cummulative incremental, it's all files changed since the previous full
backup.
 
For NT clients, by default, it's by archive bit.  There's a switch to make
this timestamp sensitive instead.

All, 

We are looking into our reporting that we have and some of the incremental
backups are extremely large, so I would like to find out what Veritas
(symantec) uses a criteria to say this file need to be backup since the last
full or last incremental.
