NAME


ipa-restore - Restore an IPA master

SYNOPSIS


ipa-restore [OPTION]... BACKUP

DESCRIPTION


Only the name of the backup needs to be passed in, not the full path. Backups are stored
in a subdirectory in /var/lib/ipa/backup. If a backup is in another location then the full
path must be provided.

The naming convention for full backups is ipa-full-YEAR-MM-DD-HH-MM-SS in the GMT time
zone.

The naming convention for data backups is ipa-data-YEAR-MM-DD-HH-MM-SS In the GMT time
zone.

The type of backup is automatically detected. A data restore can be done from either type.

WARNING: A full restore will restore files like /etc/passwd, /etc/group, /etc/resolv.conf
as well. Any file that IPA may have touched is backed up and restored.

An encrypted backup is also automatically detected and the root keyring is used by
default. The --keyring option can be used to define the full path to the private and
public keys.

Within the subdirectory is file, header, that describes the back up including the type,
system, date of backup, the version of IPA, the version of the backup and the services on
the master.

A backup can not be restored on another host.

A backup can not be restored in a different version of IPA.

Restoring from backup sets the server as the new data master. All other masters will need
to be re-initialized. The first step in restoring a backup is to disable replication on
all the other masters. This is to prevent the changelog from overwriting the data in the
backup.

Use the ipa-replica-manage and ipa-csreplica-manage commands to re-initialize other
masters. ipa-csreplica-manage only needs to be executed on masters that have a CA
installed.

REPLICATION


The restoration on other masters needs to be done carefully, to match the replication
topology, working outward from the restored master. For example, if your topology is A <->
B <-> C and you restored master A you would restore B first, then C.

Replication is disabled on all masters that are available when a restoration is done. If a
master is down at the time of the restoration you will need to proceed with extreme
caution. If this master is brought back up after the restoration is complete it may send
out replication updates that apply the very changes you were trying to back out. The only
safe answer is to reinstall the master. This would involve deleting all replication
agreements to the master. This could have a cascading effect if the master is a hub to
other masters. They would need to be connected to other masters before removing the downed
master.

If the restore point is from a period prior to a replication agreement then the master
will need to be re-installed. For example, you have masters A and B and you create a
backup. You then add master C from B. Then you restore from the backup. The restored data
is going to lose the replication agreement to C. The master on C will have a replication
agreement pointing to B, but B won't have the reverse agreement. Master C won't be
registered as an IPA master. It may be possible to manually correct these and re-connect C
to B but it would be very prone to error.

If re-initializing on an IPA master version prior to 3.2 then the replication agreements
will need to be manually re-enabled otherwise the re-initialization will never complete.
To manually enable an agreement use ldapsearch to find the agreement name in cn=mapping
tree,cn=config. The value of nsds5ReplicaEnabled needs to be on, and enabled on both
sides. Remember that CA replication is done through a separate agreement and will need to
be updated separately.

If you have older masters you should consider re-creating them rather than trying to
re-initialize them.

OPTIONS


-p, --password=PASSWORD
The Directory Manager password.

--data Restore the data only. The default is to restore everything in the backup.

--gpg-keyring=GPG_KEYRING
The full path to a GPG keyring. The keyring consists of two files, a public and a
private key (.sec and .pub respectively). Specify the path without an extension.

--no-logs
Exclude the IPA service log files in the backup (if they were backed up).

--online
Perform the restore on-line. Requires data-only backup or the --data option.

--instance=INSTANCE
Restore only the databases in this 389-ds instance. The default is to restore all
found (at most this is the IPA REALM instance and the PKI-IPA instance). Requires
data-only backup or the --data option.

--backend=BACKEND
The backend to restore within an instance or instances. Requires data-only backup
or the --data option.

--v, --verbose
Print debugging information

-d, --debug
Alias for --verbose

-q, --quiet
Output only errors

--log-file=FILE
Log to the given file

EXIT STATUS


0 if the command was successful

1 if an error occurred
