    Does anyone have something that still scales up when scaling down to an RPi?

    Thanks.

    I have 3.4 TB USb harddisks connected to my Pi4
    Shows up as /dev/sda
    Made a partition sda2 formatted with ext4 file system
    and directories I normally work with (root that is in my case)
    Every now and then I copy all data with cp -rp or cp -urp to that sda2 directory
    also wrote a script to backup mail to it.
    Or backup from the laptop with scp -p
    Never a problem.

    Backups go to both Pi4 harddisks, so even if you drop one USB harddisk you still have your data.
    scripting is a good idea, prevents typing errors.

    Does rsync not get the job done ?

    Not necessarily a Pi specific solution, but I find rsync to be fine.

    Using tar with a pipe should not be very taxing to your resources, but big tar files
    are not very manageable.

    Definetively try the rsync time machine desribed in Linux Magazine #258 (which basically means you do $ rsync -a Source_Dir First_Backup the first time you take a
    backup, and then $ rsync -a --link-dest=First_Backup Source Second_Backup for the next
    ones. That way the first backup will take long, but the next ones will be very quick.
