Data backup options in IBM Storage Scale

Backing up the data

IBM Storage Scale creates a second copy of the data within the system as backup. These secondary copies are usually point-in-time copy of the original data, and can be created on a daily, monthly, or weekly basis. In a situation where the actual data is corrupted, the system uses the backed-up copy to restore data to a previous point in time.

You can use the mmbackup command to back up the user data from a GPFS file system or independent fileset to an IBM Storage Protect server or servers. The mmbackup command can be used only to back up file systems owned by the local cluster. For more information on how to back up your data, see Back up your data and mmbackup command.

Fileset and backup

IBM Storage Scale supports backup from independent filesets in addition to backup of the whole file system. For more information on fileset backup, see Filesets and backup. If you are planning to use IBM Storage Protect to back up IBM Storage Scale file systems, see Backup considerations for using IBM Storage Protect
