# Use command restore-to-file
|
||
|
|
This command gives users the ability to restore a backup to a `raw` image or a `qcow2` image. If the backup is based on a backing file, users should provide the backing file as a `qcow2` image with `--backing file` parameter.
|
||
|
|
|
||
|
|
## Instruction
|
||
|
|
1. Copy the yaml template
|
||
|
|
|
||
|
|
1.1 Without backing file: Make a copy of `examples/restore_to_file.yaml.template` as e.g. `restore.yaml`.
|
||
|
|
|
||
|
|
1.2 With backing file: Make a copy of `examples/restore_to_file_with_backing_file.yaml.template` as e.g. `restore.yaml`.
|
||
|
|
|
||
|
|
1.2.1 Set argument `backing-file` by replacing `<BASE_IMAGE>` with your base image, e.g. `rancher/longhorn-test:baseimage-ext4`.
|
||
|
|
|
||
|
|
1. Set host node on which the output file should be placed by replacing `<NODE_NAME>`.
|
||
|
|
|
||
|
|
2. Specify the host path of output file by modifying field `hostpath` of volume `disk-directory`. By default the directory is `/tmp/restore/`.
|
||
|
|
|
||
|
|
3. Set the first argument (backup url) by replacing `<BACKUP_URL>`, e.g. `s3://backupbucket@us-east-1/backupstore?backup=backup-bd326da2c4414b02&volume=volumeexamplename`. Do not delete `''`.
|
||
|
|
|
||
|
|
4. Set argument `output-file` by replacing `<OUTPUT_FILE>`, e.g. `volume.raw` or `volume.qcow2`.
|
||
|
|
|
||
|
|
5. Set argument `output-format` by replacing `<OUTPUT_FORMAT>`. Now support `raw` or `qcow2` only.
|
||
|
|
|
||
|
|
6. Set S3 Credential Secret by replacing `<S3_SECRET_NAME>`, e.g. `minio-secret`.
