A backup policy for the backup destination disk or tape must be set for the transaction volume registered in the Storage Server. When data is backed up to both disk and tape, a backup policy must be set for each of them.
Set the following backup policy.
The number of preservation generations
This refers to how many generations of backup data should be retained.
Interval days
This refers to the number of days between one backup and the next. If the specified number of days is exceeded, the number of elapsed days is displayed when the execution status display command is executed.
Use "11.2.1.5 acmbkpolset (Disk backup policy setting command)" to set the backup policy.
The following command execution example sets 3 as the number of preservation generations for the device (/dev/dsk/c1t1d0s6).
[For Solaris]
# /opt/FJSVswstc/bin/acmbkpolset -s 3 /dev/dsk/c1t1d0s6 /dev/dsk/c1t1d0s6 acmbkpolset completed # |
Note
Even if the number of interval days is specified, the Tape Backup function of AdvancedCopy Manager does not automatically back up data. This value is used only to prompt the user to perform backup when the number of backup interval days is exceeded.
When you set a backup policy, there must be as many registered backup volumes as required to perform backup according to the specified backup policy. For the required number of backup volumes, refer to "Preparing a backup volume" in "Operation Design" in the backup operation chapter of the "ETERNUS SF AdvancedCopy Manager Operator's Guide" for the operating system of the target Storage Server.
Even if the number of backup volumes required for the backup was not registered when backup policies for synchronized high-speed backup were set, the number can be set by default provided the number of backup volumes that are required for snapshot fast backup have already been registered. In this case, however, it may not be possible to execute synchronized high-speed backup.
Point
Information on a defined backup policy can be viewed using "11.2.1.6 acmbkpoldisp (Disk backup policy display command)".
Set the tape backup management class. Define the following in the management class:
Generation management storage pool name
The name of the storage pool used to store backup data when a backup with generation management is executed
Number of preservation generations
The number of generations of backup data that should be preserved
Day management storage pool name
The name of the storage pool used to store backup data when a backup with day management is executed
Preservation days
The number of days for which backup data should be preserved
The starting point for the "Preservation days" is the day of the backup start time displayed at "TapeCopy-Date" by the command 11.2.2.9 acmhistdisp (History information display command).
The tape backup management class can be set using "11.2.1.11 acmtpmgmtclassset (Tape backup management class setting command)".
The following command execution example creates tape backup management class ACM_CLASS1 for backup with generation management to preserve five generations in COPYPOOL and for day management for 30 days in ARCPOOL.
[For Solaris]
# /opt/FJSVswstc/bin/acmtpmgmtclassset -g ACMPOOL1 -d ARCPOOL -s 5 -t 30 ACM_CLASS1 ACM_CLASS1 acmtpmgmtclassset completed # |
Point
Information on the tape backup management class that has been set can be viewed using "11.2.1.12 acmtpmgmtclassdisp (Tape backup management class display command)".
Set the tape backup policy. Define the following in the tape backup policy:
Tape backup management class name
The name of the tape backup management class used for backup operation. When backup is performed, data is stored in the storage pool defined in the specified tape backup management class. The backup is managed according to the number of preservation generations and preservation days defined in the tape backup management class.
Number of interval days for generation management
The number of days before another backup with generation management is performed after a backup with generation management is performed. If the specified number of days is exceeded, the user will be prompted to perform backup when "11.2.2.14 acmexecstat (Execution status display command)" is executed.
Number of interval days for day management
The number of days before another backup with day management is performed after a backup with day management is performed. If the specified number of days is exceeded, the user will be prompted to perform backup when "11.2.2.14 acmexecstat (Execution status display command)" is executed.
The tape backup policy can be set using "11.2.1.8 acmtpbkpolset (Tape backup policy setting command)".
The following command execution example sets a tape backup policy for the device (/dev/dsk/c1t1d0s6) with ACM_CLASS1 as the tape backup management class and with 10 as the number of interval days for backup with generation management.
[For Solaris]
# /opt/FJSVswstc/bin/acmtpbkpolset -i 10 -c ACM_CLASS1 /dev/dsk/c1t1d0s6 /dev/dsk/c1t1d0s6 acmtpbkpolset completed # |
Note
Even if the number of interval days is specified, the Tape Backup function of AdvancedCopy Manager does not automatically perform backup. The value specified here is used to urge the user to perform backup if the user fails to perform backup within the specified number of interval days.
Point
Information on a defined tape backup policy can be viewed using "11.2.1.9 acmtpbkpoldisp (Tape backup policy display command)".
