Rock pi 4 emmc back up

#21

I updated the script, please download it again.

Thank you for helping to find the bug.

This is because -e option was added in the previous version. I provided this parameter when I tested it.

However, if this parameter is not specified when running it, it will add an extra \(backslash) to rsync and cause a bug.

Plug in sd card and restart to verify the backup was successful.

Can a script be made to backup a micro-sd card with a card reader with a Linux OS on that you can run on a PC Linux OS perhaps that only backup used space?
It would be very useful since using the dd command takes 64GB space to backup a 64GB micro-sd card.
Some OS’s like LibreELEC also doesn’t have the same UI as Ubuntu so it’s not possible to run a script directly on these OS’s from a micro-sd card and a PC script would be useful in such a case.
