NAME

6       ipa-restore - Restore an IPA master
7

SYNOPSIS

9       ipa-restore [OPTION]... BACKUP
10

DESCRIPTION

12       Only  the  name of the backup needs to be passed in, not the full path.
13       Backups are stored in  a  subdirectory  in  /var/lib/ipa/backup.  If  a
14       backup is in another location then the full path must be provided.
15
16       The  naming convention for full backups is ipa-full-YEAR-MM-DD-HH-MM-SS
17       in the GMT time zone.
18
19       The naming convention for data backups is  ipa-data-YEAR-MM-DD-HH-MM-SS
20       In the GMT time zone.
21
22       The  type  of  backup  is automatically detected. A data restore can be
23       done from either type.
24
25       WARNING:  A  full  restore  will  restore   files   like   /etc/passwd,
26       /etc/group,  /etc/resolv.conf  as  well.  Any  file  that  IPA may have
27       touched is backed up and restored.
28
29       An encrypted backup is also automatically detected and the root keyring
30       and gpg-agent is used by default. Set GNUPGHOME environment variable to
31       use a custom keyring and gpg2 configuration.
32
33       Within the subdirectory is file, header, that  describes  the  back  up
34       including  the  type,  system,  date of backup, the version of IPA, the
35       version of the backup and the services on the master.
36
37       A backup can not be restored on another host.
38
39       A backup can not be restored in a different version of IPA.
40
41       Restoring from backup sets the server as the new data master. All other
42       masters  will  need to be re-initialized. The first step in restoring a
43       backup is to disable replication on all the other masters. This  is  to
44       prevent the changelog from overwriting the data in the backup.
45
46       Use the ipa-replica-manage and ipa-csreplica-manage commands to re-ini‐
47       tialize other masters. ipa-csreplica-manage only needs to  be  executed
48       on masters that have a CA installed.
49

REPLICATION

51       The  restoration  on other masters needs to be done carefully, to match
52       the replication topology, working outward from the restored master. For
53       example,  if  your  topology is A <-> B <-> C and you restored master A
54       you would restore B first, then C.
55
56       Replication is disabled on  all  masters  that  are  available  when  a
57       restoration is done. If a master is down at the time of the restoration
58       you will need to proceed  with  extreme  caution.  If  this  master  is
59       brought  back  up  after  the  restoration  is complete it may send out
60       replication updates that apply the very changes you were trying to back
61       out.  The  only  safe  answer  is  to  reinstall the master. This would
62       involve deleting all replication agreements to the master.  This  could
63       have  a  cascading effect if the master is a hub to other masters. They
64       would need to be connected to other masters before removing the  downed
65       master.
66
67       If  the restore point is from a period prior to a replication agreement
68       then the master will need to be re-installed.  For  example,  you  have
69       masters  A and B and you create a backup. You then add master C from B.
70       Then you restore from the backup. The restored data is  going  to  lose
71       the replication agreement to C. The master on C will have a replication
72       agreement pointing to B, but B won't have the reverse agreement. Master
73       C  won't be registered as an IPA master. It may be possible to manually
74       correct these and re-connect C to B but  it  would  be  very  prone  to
75       error.
76
77       If  re-initializing  on  an  IPA  master  version prior to 3.2 then the
78       replication agreements will need to be  manually  re-enabled  otherwise
79       the re-initialization will never complete. To manually enable an agree‐
80       ment  use  ldapsearch  to  find  the  agreement  name   in   cn=mapping
81       tree,cn=config.  The  value  of nsds5ReplicaEnabled needs to be on, and
82       enabled on both sides. Remember that CA replication is done  through  a
83       separate agreement and will need to be updated separately.
84
85       If  you  have older masters you should consider re-creating them rather
86       than trying to re-initialize them.
