5.4.2 Backup

To recover director data files to a backup point, it is necessary to have backed up the director data files beforehand.

The following example shows how to back up the director data files after the day's operations have finished.

[Figure : Backing Up Director Data Files ]

The following procedure is used to take a backup that can be used to recover from a malfunction.

[Figure : Back Up Procedure]

1. Execute the shundbackup command with the -b option to declare the start of the backup.

   shundbackup -s director identifier -b

2. Back up the director data files.

   The directory specified by the DataFileFolder parameter in the director environment file contains a directory with the same name as the director identifier. Back up all the files from that directory.

   Use the following operating system commands or a disk device copy function to perform the backup:

   

   copy command, etc.

   

   cp command, etc.

3. Execute the shundbackup command with the -e option to declare the end of the backup.

   shundbackup -s director identifier -e

• Back up the director data files to a different disk from that where the directory containing the director data files is located.
• If after the backup start declaration has been executed, an error occurs during a backup that uses an operating system command or a disk device copy function, do not execute the backup end declaration. Instead, execute the shundbackup command with the -c option to cancel the backup start declaration and then, after eliminating the cause of the error, execute the backup start declaration again.

The date and time of the latest backup can be verified with the shundstate command. Refer to 6.2.3 Monitoring Director Operation Information for more information on the content displayed by the shundstate command.
