Incremental backup: backup too big and files that are backed-up are not modified from last full backup
this is my first post in the blog, so... hi to all.
I describe first the enviroment:
Master Server: Netbackup 188.8.131.52 on Windows 2008 R2.
Client Server: Virtual Machine (agentless) with raw device attached on Windows 2008 R2. We have mapped the raw device and we have a shared folder created on.
The full backup is about 1.2 TB (scheduled once a week) and the incremental backups are approximately 280 GB (sceduled all afternoon). We don't have this movimentation of data, i think that the right size of incremental backup should be about 50 GB as max.
I have checked using the restore tools which files are backed-up, and in different days i see the same files in the backup. Files that have as last modified date 2012 or before.
We have disabled the antivirus too, but same story.
Could someone help me to understand?
ps: sorry for my elementary english.
