Backing up storage groups to a secondary volume
This section describes the processing flow for backing up storage groups to a secondary volume on
a single-server system.
To back up a storage group:
1. Resynchronize the copy groups
Execute EX_DRM_RESYNC on the database server to resynchronize the copy groups.
Resynchronizing the copy groups before you perform backup enhances the speed of backup
processing. In this example, the copy group name is VG01,vol01.
DBServer > EX_DRM_RESYNC Operation_A -cg VG01,vol01 -copy_size 7
2. Back up the storage group to a secondary volume.
Back up the storage group. To perform backup, execute EX_DRM_EXG_BACKUP. Specify the
operation ID Operation_A as the argument. In this example, delete the transaction log file to
execute a cold backup.
DBServer > EX_DRM_EXG_BACKUP Operation_A -mode cold -transact_log_del
Specify -mode cold to execute a cold backup. Even when -mode cold is not specified, a cold
backup will be executed as if this option had been specified.
Specify -mode online to execute an online backup. When an online backup is executed, you
cannot specify the -transact_log_del option.
