    No, you do what you're good at, and I think GH has found it.

    OR

    Can a chronological backup system be set up? So you may have two weekly backups (if there was a problem you would be able to go back 1 week or two weeks). Same for daily backups would it be possible to have 6? where the oldest would be overwritten. So in total there would be 8 backups per site allowing for restoration from 1,2,3,4,5,6,7,14 days?

    Also is it possible to set backups to run throughout a 24hour day instead of at a particular time to reduce server load? Is it worth it?
    If you choose incremental backup in cpanel, you get a misnomer of a backup. All that means is that cPanel will use rsync instead of copy - tar - gzip, which results in a substantially lower load.

    rsync does have an option to do TRUE incremental backups, where you could have a series of daily backups that include only the changed files.

    I found a lot of backup scripts out there using rsync.

    rsync backup script - now Incremental with little storage impact

    As for linmiting load further:
    Unused by cPanel, there is an option to limit bandwidth:
    --bwlimit=KBPS
    This option allows you to specify a maximum transfer rate in
    kilobytes per second. .... etc ...

    Now, I am not sure if this helps on a backup within a server, but is meant I think to work across servers.
