How does dietpi-backup actually works?

General Discussion

What directories are backed up?
Is it possible to add/exclude directories?
Every time it runs, the previous backup is replaced for the new backup?
The default backup directory is /mnt/dietpi-backup/. Can i change it in order to do the backup to an external drive?

Thanks

Hi,

many thanks for your request. I will try to answer your questions one by one

  1. What directories are backed up?
  • dietpi-backup will do a complete system back or restore of the Linux RootFS file-system (/) using rsync
  1. Is it possible to add/exclude directories?
  • yes, thats possible. There is an option inside dietpi-backup called Custom Filters
  1. Every time it runs, the previous backup is replaced for the new backup?
  • there is basically just one backup. A new run of dietpi-backup will copy changed or updated files only, like an incremental backup. Therefore it’s much faster than the initial one
  1. The default backup directory is /mnt/dietpi-backup/. Can i change it in order to do the backup to an external drive?
  • yes, taget file system can be changed. There is an option inside dietpi-backup called Location
