# 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`.
