In "4.1 Backup Operations for Symfoware", the disks connected to the Symfoware server are taken as backup volumes, while in backup server operation, the disks connected to a backup server can be specified as backup volumes.
This configuration allows you to use tape backup software (ISV) to perform tape backup without putting any load on the business server.
Figure 4.5 System configuration
AdvancedCopy Manager can back up Symfoware database space on a per database space or per log group basis.
AdvancedCopy Manager takes as a transaction volume a partition to which database space to be backed up is allocated.
In backup operation on a per database space basis, the transaction volume is backed up to a backup destination volume (backup volume).
In backup operation on a per log group basis, all the database space contained in a log group is defined as transaction volumes respectively and all those transaction volumes are backed up.
In Symfoware backup server operation, transaction volumes and backup volumes should be registered as replication source and destination volumes respectively for replication management function.
Note
In backup operation on a log group basis, partitions to which all the database space contained in a log group is allocated should be registered as transaction volumes. If even one partition is not registered, AdvancedCopy Manager cannot back up that database space that is not registered and maintain consistency with inter-table relationships at database recovery time.
AdvancedCopy Manager creates a recovery control file that stores data required for database recovery at backup time, and manages it on a per backup volume basis. Since the recovery control file is created on Symfoware server, when performing tape backup on a backup server, use the operating system's copy function or normal replication management function to save to the backup server.
Archive log is not backed up. When backing up an archive log, see the Symfoware Server manual to do it.
AdvancedCopy Manager can recover database space on a per Symfoware database space or per log group basis. Refer to notes described in "12.7.3 swsrprestore_symfoware(Symfoware recovery execution command)" when recovering to two or more database space at the same time.
AdvancedCopy Manager performs recovery processes as follows:
Copy a backup volume (copy destination volume) to a transaction volume (copy source volume).
When recovering to the most up-to-date status or a specific point in time, apply an archive file based on the recovery control file.
Point
When backing up archive logs, specify the file to which archive log backup file names were written at recovery time (archive log backup destination names are listed) at recovery time to recover.
Note
Recovery cannot be implemented if the specified "file that includes the name of the archive log's backup location" contains an archive backup file that is backed up on a MT (tape device).
Since you must use AdvancedCopy Manager to recover Symfoware database spaces that were backed up with AdvancedCopy Manager, you cannot directly recover from any backup volumes that were backed up on tape or other secondary media.
