-To restore a backup made via bpcdump:
-
- - Attach the external sata drive
- - sudo esata mount
- - Select the backup to restore, for example ve1200-20080605
- - Examine the contents of /media/esata/ve1200-20080605/info
- - Ensure a partition (preferably an LVM2 LV) exists to restore into, and that
- its size is at least as large as the size identified in the 'info' file.
- Note the partition's device name, for example /dev/vg0/ve1200.
- - md5sum /media/esata/ve1200-20080605/image
- Verify the above command outputs the same signature as contained within
- /media/esata/ve1200-20080605/image.md5sum. If they are not the same,
- the selected image has become corrupted and another backup should be
- selected to restore.
- - dd_rescue -Ay 8192 /media/esata/ve1200-20080605/image /dev/vg0/ve1200
- - Examine the output from dd_rescue; ensure there are no errors reported and
- that it returns without error. This command will take some time.
- - dd if=/dev/vg0/ve1200 bs=<imageblocksize> | md5sum
- The emitted MD5 signature should match
- /media/esata/ve1200-20080605/image.md5sum.
- - The partition is now ready to be mounted for use by the BackupPC VE. It may
- be necessary to create the VE's conf file in /etc/vz/conf.
- - sudo vzctl start 1200
- - Verify correct operation of the restored BackupPC VE.
-
-This process will be replaced by a script, bpcrestore:
-
- - To restore an old version of VE 1200 over itself:
- bpcrestore /media/esata/ve1200-20080605
- (this command will create VE 1200 if it doesn't exist on the HN on which
- bpcrestore was executed.)
-
- - To restore an old version of VE 1200, implicitly creating a new VE 1201:
- bpcrestore /media/esata/ve1200-20080605 1201
-
- - Perhaps the script will instead be bpcbackup --restore, akin to vzdump's
- operation.
