Adding the replicas back on to each server by replicating them from the copy on the
DSMASTER server.
Delores and her team have a pretty good idea which replicas were held by each server, but they
can read the header of the backup files for each server to see a list of the replicas that were on
the server at the time of the last backup.
Re-creating the roll-forward log configuration after the servers are back on line (since the
restore turns it off and resets the settings to the default), and creating a new full backup as a
baseline to prepare for any other failures that might happen before the next unattended full
backup is scheduled.
(These steps are explained in more detail in
Section 17.7, “Recovering the Database If Restore
Verification Fails,” on page 459
.)
Delores and her team have a lot of work to do, but they can get the tree itself up relatively quickly,
and they can expect to recover the eDirectory identity for all of their servers.
17.9 Disaster Recovery Plan using DSBK
A disaster recovery plan enables you to recover your disk back to the configuration at the time of
corrpution. You have to backup your server’s disk to a remote location, so that you can recover the
server even if the operating system gets corrupted.
Section 17.9.1, “Disaster Recovery Plan on Linux,” on page 469
17.9.1 Disaster Recovery Plan on Linux
To take a backup of the server’s disk:
1
Configure DSBK:
1a
Create a file
dsbk.conf
in
/etc
.
1b
Create a temporary file. For example,
/tmp/dsbk.tmp
.
1c
Specify the location of the temporary file created in the previous step in the
/etc/
dsbk.conf
file.
2
Mount the server's disk to a remote machine. For example,
/root/dsbkBkp
.
3
Set the custom backup location using the following command:
dsbk setconfig -L -T -r /root/dsbkBkp
4
Take a complete backup along with NICI, to the remote location file system:
dsbk backup -f <backup file location> -l <log file location> -e <password
for backup> -t -b
For example,
dsbk backup -f /root/dsbkBkp/fb1.bak -l /root/dsbkBkp/fb1.log -
e novell -t -b
.
NOTE:
The
-e
option is used to backup NICI. In the xample,
novell
is password for NICI
Backup. You may choose your own password, and the same password must be used during
NICI restore.
5
To take incremental backups, use the following command:
dsbk backup -f <incremental backup file location> -l <incremental log file
location> -t -i
