5.3.2 Backup

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

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

[Figure : Backing up Director Data Files]

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 disk other than the disk where the director data files are located.
• Back up the director data files if any of the following commands have been executed:
  • if the shundimport command has been executed with the -n option to import or delete a record without collecting the operation log file
  • if the shundrecover command has been executed with the -p option to recover to a backup point or a specified point
• 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.
