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. If there is
a big difference between the primary volume data and the secondary volume data when data
is backed up from the primary volume to the secondary volume, the backup might take a while.
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.
Execute EX_DRM_EXG_BACKUP to back up the storage group. 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.
