- backup_storage_hook |
- If set, the content of every file to backup is sent to a hook. The
- hook receives the data for each file on stdin. It should echo the
- transformed data to stdout. Anything the hook prints to stderr will
- be printed in the vttablet logs.
- Hooks should be located in the vthook subdirectory of the
- VTROOT directory.
- The hook receives a -operation write or a
- -operation read parameter depending on the direction
- of the data processing. For instance, write would be for
- encryption, and read would be for decryption.

backup_storage_compress |
This flag controls if the backups are compressed by the Vitess code.
By default it is set to true. Use
--backup_storage_compress=false to disable.
- This is meant to be used with a --backup_storage_hook
- hook that already compresses the data, to avoid compressing the data
- twice.

+ backup_storage_block_size |
+ If --backup_storage_compress is true, backup_storage_block_size sets the byte size for each block while compressing (default is 250000).
+ |
+
+
+ backup_storage_number_blocks |
+ If --backup_storage_compress is true, backup_storage_number_blocks sets the number of blocks that can be processed, at once, before the writer blocks, during compression. It should be equal to the number of CPUs available for compression. (default 2)
