Subfilebackup

The subfilebackup option specifies whether to enable adaptive subfile backup.

Note:
  1. To use the subfilebackup option, the server must have subfile yes or subfile client set. Ask your Tivoli® Storage Manager administrator to set the correct values.
  2. You can use open file support with subfile backup operations.
  3. The subfilebackup option does not work correctly for migrated files. If you use a combination of subfilebackup yes and subfilebackup no for migrated files, your data might be corrupted on the server.
  4. Adaptive subfile backup can be used with selective backups, incremental backups, and on file-level backups of VMware virtual machines (Backup VM commands where VMBACKUPTYPE=FILE is specified).
  5. Adaptive subfile backup processing occurs only when you back up files; it is not used for archive operations.
  6. Restoring files that were backed up with adaptive subfile backup is accomplished by using the dsmc restore.

Supported Clients

This option is valid for all Windows clients. The server can also define this option. The Tivoli Storage Manager client API does not support this option.

Options File

Place this option in the client options file (dsm.opt). You can set this option on the Backup tab of the Preferences editor.
