Gzipped files NOT backed up by differential incremental backup.
On day 1, a data file is created. It is backed up by the daily incremental backup.
On day 4, that same data file is compressed with gzip. It is SKIPPED by that night's incremental backup!
The gzipped version of the file is not backed up until the weekly full backup!
I know why: The modification time on the file is not changed by gzip. Netbackup goes by inode and modification time.
Can Netbackup be instructed to backup files if they're renamed? What other options do I have?
