Restore the Backup File

Restore to root.kct

1. Rename the existing root.kct file:

   mv /var/lib/er2/db/root.kct /var/lib/er2/db/root.kct.orig

2. Run the er2-recovery command:

   # Where '/tmp/er2-backup.bak' is the backup file to recover ER2 from er2-recovery -b /tmp/er2-backup.bak -w /var/lib/er2/db/root.kct

   
   To recover or restore from a kct file:

   # Where '/tmp/er2-backup.kct' is the backup file to recover ER2 from er2-recovery -i /tmp/er2-backup.kct -w /var/lib/er2/db/root.kct

3. Give ER2 ownership of the root.kct file:

   chown erecon:erecon /var/lib/er2/db/root.kct; chmod go-r /var/lib/er2/db/root.kct

4. (Optional) Once the restore operation has been verified to be successful, the original database file /var/lib/er2/db/root.kct.orig may be deleted.

Restore to root.rdb

1. Rename the existing root.rdb file:

   mv /var/lib/er2/db/root.rdb /var/lib/er2/db/root.rdb.orig

2. Run the er2-recovery command:

   
   To recover or restore from a bak file:

   # Where '/tmp/er2-backup.bak' is the backup file to recover ER2 from er2-recovery -b /tmp/er2-backup.bak -w /var/lib/er2/db/root.rdb

   
   To recover or restore from a kct file:

   # Where '/tmp/er2-backup.kct' is the backup file to recover ER2 from er2-recovery -i /tmp/er2-backup.kct -w /var/lib/er2/db/root.rdb

   
   To recover or restore from a rdb folder:

   # Where '/tmp/er2-backup.rdb' is the backup folder to recover ER2 from er2-recovery -i /tmp/er2-backup.rdb -w /var/lib/er2/db/root.rdb

3. Give ER2 ownership of the root.rdb database folder:

   chown -R erecon:erecon /var/lib/er2/db/root.rdb; chmod -R go-r /var/lib/er2/db/root.rdb

4. (Optional) Once the restore operation has been verified to be successful, the original database folder /var/lib/er2/db/root.rdb.orig may be deleted.
