Docker Volume Backup
A simple script which creates tarballs from docker volumes and restores them.
Usage
Backup a single volume
./dvbackup.sh backup <volume_name> <path/to/tarball.tar>
Creates a tarball from the contents of the volume.
Restore a single volume
./dvbackup.sh restore <path/to/tarball.tar> <volume_name>
Restores the tarball into the volume. This is destructive, all old contents will be removed from the volume. The volume must already exist.
Backup all named volumes
./dvbackup.sh backup_all
Creates backups from all volumes which do not only contain the character
set [0-9a-f].
This command will output a <volume_name>.tar file for every found
volume in the current working directory.
Restore volumes
./dvbackup.sh restore_all [volume.tar...]
Restores all given tarballs into their respective volumes. The volumes
must already exist and the operation is destructive in the same way
as the restore operation. The default behaviour is to ask before
continuing, this can be overridden by setting DVB_I_KNOW_WHAT_I_DO=y.
Volumes can be created implicitly by setting DVB_CREATE_VOLUME=y.
