5.1.3 Backup Start Declaration and End Declaration

An operating system command or disk device copy function is used to back up director data files.

Backup start and end declarations are used to synchronize the data update process and the director data file backup.

This operation prevents data that is in the process of being updated from being generated during a backup, which in turn ensures the consistency of the backup data.

It is recommended that the series of backup operations that must take place between the backup start declaration and the backup end declaration be performed during a period when there is as little update activity going on as possible. This will minimize the time required to complete the backup.
