Backup data saved to a disk can be copied to a tape later. The data thus saved to the tape is managed as backup history information. The same generation number as the backup history on the source disk is assigned to this backup history for management.
This function can be used in the following cases:
You want to keep backup data on both a disk and tape but want to write backup data to tape some time later than writing to the disk.
In this case, when performing backup, specify DISK in the -m option to perform backup to only a disk.
Even though you performed backup to save data to both a disk and tape, you failed in an attempt to back up data to tape because the tape ran out.
In this case, the backup to the disk was successful and so you can add tape and then create backup history information on tape by using the copy function.
Follow the procedure below for copying to tape:
Determine the backup history to be copied. Use "11.2.2.9 acmhistdisp (History information display command)" to display backup history information. If a backup history exists on the disk, a relative generation number is displayed in the "Generation" field. From the backup history information on the disk, select the history you want to copy to tape.
A command execution example is shown below.
[For Solaris]
# /opt/FJSVswstc/bin/acmhistdisp /dev/dsk/c1t1d0s6 Generation Management Backup Server=server1 Device/dev/dsk/c1t1d0s6 Mount-Point=/mnt/Tran1 (ufs) Generation Version Backup-Date Backup-Device Status Execute Tape-Gen 1 10 2004/11/12 22:00 /dev/dsk/c1t0d2s6 succeeded ---- 1 2 9 2004/11/11 22:00 /dev/dsk/c1t0d4s6 succeeded ---- - Day Management Backup Server=server1 Device=/dev/dsk/c1t1d0s6 Mount-Point=/mnt/Tran1 (ufs) TapeCopy-Date Backup-Date Expiration-Date # |
Execute "11.2.2.2 acmtphistcopy (Tape copy command)" for copy to tape.
To copy a specific backup history
Use the -g or -v option to specify the target backup history using either the relative generation number or the absolute generation number.
To copy the latest backup history
If no backup history is specified, the Tape Backup of AdvancedCopy Manager copies the latest backup history on the disk it manages.
Other tape-related specifications
Specify the -b option to select generation management or day management.
The following command execution example copies the backup history with relative generation number 2, displayed in step 1, to tape.
[For Solaris]
# /opt/FJSVswstc/bin/acmtphistcopy -g 2 /dev/dsk/c1t1d0s6 /dev/dsk/c1t1d0s6 acmtphistcopy completed # |
This completes the procedure for copying to tape.
