help with tar incremental
I want to make incrementals backups.
So I do:
tar -g /var/snap -C /var/www -czf backup.tar.gz .
The next day, when I execute the same (only change the name of the file) it backup everything again.
If I execute 1 tar after the first it works fine ... but in dicfferents days .. it doesnt work ...
How I have to do ?? perhaps touch <CURRENT DATE> /var/snap before the tar ??
thanx for any help
