Command
weka fs downloadUse the following command line to create a filesystem from an existing snapshot:
weka fs download <name> <group-name> <total-capacity> <ssd-capacity> <obs> <locator>
Parameters
| Name | Type | Value | Limitations | Mandatory | Default |
|---|---|---|---|---|---|
| name | String | Name of the filesystem to be created | Yes | ||
| group-name | String | Name of the filesystem group in which the new filesystem will be placed | Yes | ||
| total-capacity | Capacity | Total capacity of the downloaded filesystem | Yes | ||
| ssd-capacity | Capacity | SSD capacity of the downloaded filesystem | Yes | ||
| obs | String | Object store name for tiering | Yes | ||
| locator | String | Object store locator obtained from a previously successful snapshot upload | Yes | ||
| additional-obs | String | An additional objec-store name. In case te data to recover resides in two object stores (a second object-store attached to the filesystem, and the filesystem has not undergone full migration). This object-store will be attached in a read-only mode. | The snapshot locator must reside in the primary object-store supplied in the obs parameter | No | |
| snapshot-name | String | The downloaded snapshot name. | No | The uploaded snapshot name | |
| access-point | String | The downloaded snapshot access point | No | The uploaded access point |
The locator is either a locator saved previously for disaster scenarios, or can be obtained using the weka fs snapshot command on a system with a live filesystem with snapshots.
Note:
- Due to the bandwidth characteristics and potential costs when interacting with remote object stores it is not allowed to download a filesystem from a remote object-store bucket. If a snapshot on a local object-store bucket exists, it is advisable to use that one. Otherwise, follow the procedure in Recover from a remote snapshot.
- For encrypted filesystem, when downloading the same KMS master-key should be used to decrypt the snapshot data. For more information about encryption, see KMS management in the Content Software for File User Guide.
