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 and  gpg-agent  is
       used  by  default.  Set  GNUPGHOME  environment  variable to use a custom keyring and gpg2
       configuration.

       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.

       --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
