# snap-sync
## About
This bash script sends incremental snapshots to another drive for backing up
data. Plug in and mountany btrfs-formatted device you want your system to be
backed up to (like a USB drive). When you run the script you will be prompted
to select a mounted btrfs device.
The script iterates through all snapper configurations. For each configuration
it creates a new local snapshot. If you have never synced to the specified
device you will be prompted to enter a directory on the device where the backup
snapshots will go. Additionally you are show the location of the backed up
snapshot. If you have performed a backup to this device before, only the changes
since the last backup have to be sent.
snapper is required.
