This topic describes the backup disk-store command in gfsh, the VMware Tanzu GemFire command-line interface.
Use this command to back up persistent data from all members to the specified directory.
The specified directory must exist on all members, but it can be a local directory on each machine. This command ensures that backup files are not corrupted by concurrent operations. Backing up a running system using the operating system copy command is not recommended.
You can also use this command to perform an incremental backup. See Creating Backups for System Recovery and Operational Management for more information about incremental backup.
Availability: Online. You must be connected in gfsh to a JMX Manager member to use this command.
Syntax:
backup disk-store --dir=value [--baseline-dir=value]
| Name | Description |
|---|---|
| ‑‑dir | Required. Directory to which backup files are written. |
| ‑‑baseline-dir | Directory that contains the baseline backup used for comparison during an incremental backup. An incremental backup operation backs up any data that is not present in the directory specified in ‑‑baseline-dir. If the member cannot find previously backed up data or if the previously backed up data is corrupt, the command performs a full backup on that member. |
