understanding incremental backup
Firstly, I did google and read the documentation on backups..
I setup new server and due to the size i am consider incremental. Would love to move the files to remote storage but rsync is not an option with ovh. Anyway that's not my question :-)
my question:
If i set Incremental On, and select Daily Sunday. I assume on first Sunday a full backup is made, then on next sunday only changes from last one, what happens on third sunday?
-Does it perform full again?
-Does it backup changes from first sunday? if which case what happens to the changed files from Full backup> first sunday.
-Does it backup all changed files since full backup?
retention set to 1
thanks

Hey there! I think you'll want to have the Retention option set to at least 2 in order for this to work well - that will get you the following:
First Sunday - the full backup will run with all the data
Second Sunday - the first incremental backup run where only changes are backed up.
Third Sunday - with your retention set to 2, the third time would be an additional incremental backup, but the previous Sunday would be removed. This would leave you with your original backup with all changes since the original in the most recent backup.0 -
Ok this will work. Thanks.!

You're welcome!

As the incremental starts to grow, how to do i trigger a new full backup? delete the backups?

If you wanted to do that you could, although the incremental backup will help keep things smaller.
