    Which uses less resources?
    Incemental or compressed backups?

    Depends on the resources in question.. disk space? CPU time? bandwidth?

    I personally run full compressed backups daily (modified to use rsync), and then rsync them to a remote server nightly. I prefer full backups, as I don't have to restore a bunch of incrementals, always have all the info, etc. Full backups take more time and disk space, but doing that with the rsync modifications uses less (or possibly about the same) bandwidth as incrementals, assuming these are moving offsite.

    zat help any? :confused:

    By inremental I mean full site backups - but only backing up the data that has changed. Rather than just compressing a full backup and overwriting the old one.

    THe backups are going to a secondary drive, not offsite.

    I'm just wondering which is easier on the CPU/RAM.

    Go on, have a guess
    Incrementals - low CPU; low memory; high disk space; lower disk I/O; convenient for small file(s) restores; inconvenient for storing and safe keeping off-server.

    Full - higher CPU; higher memory; high disk I/O (the way it's done the cPanel way); lower disk space; less convenient for small file(s) restores; convenient for storage and keeping off-server.

    That probably covers it ;)
