9.2. RESTORING A BACKUP
If you have a directory with a backup created using
ipa-backup
, you can restore your IdM
server or the LDAP content to the state in which they were when the backup was
performed. You cannot restore a backup on a host different from the host on which the
backup was originally created
Is it meant if I clean install using same host name ( a total new host) and restore using the backup
it will fail right ?.. The disaster meant all hosts fail I need clean install the first host can I use the that restore method ?

it can turn on the ldap but the web page not allow to login ...mostly it related to ?
on which system do you have trouble accessing the web GUI? the master?
In this case, can you paste the exact command you ran for restore, and the exact error message you see when trying to authenticate to the web? The httpd error log may also be helpful (/var/log/httpd/error).

ic ..but the full restore can success run in clean installed
master with new CA overwrite?
e.g. master with CA and ldap all crashed with replication
servers but data aslo crashed...can it be use as restore using
the same hostname and rebuild the replication agreements with
others?
Hi,
yes, the doc explains how to restore in a multi-master environment:

tried such recover in v3 it seem it broken the
relationship of
others agreement. or I missed the backup of some files.
Hi,
you can find the doc for 4.5 in
https://access.redhat.com/documentation/en-us/red_hat_enterp rise_linux/7/html/linux_domain _identity_authentication_and_ policy_guide/backup-restore
<https://access.redhat.com/documentation/en-us/red_hat_enter >prise_linux/7/html/linux_domai n_identity_authentication_and_ policy_guide/backup-restore
<https://access.redhat.com/documentation/en-us/red_hat_enter prise_linux/7/html/linux_domai n_identity_authentication_and_ policy_guide/backup-restore
<https://access.redhat.com/documentation/en-us/red_hat_enter >>prise_linux/7/html/linux_domai n_identity_authentication_and_ policy_guide/backup-restore
The full backup of a master with CA also contains the certs
and the CA.
HTH,
Flo
is it possible to use very old vm image plus the
regular ldif
backup recovery?

If you have a full backup of a master with a CA
and have
saved it
off-machine and your machine dies then you can
re-install
using the
EXACT SAME OPTIONS.
Then restore the backup. Then re-initialize all other
masters (this
should all be documented already).
If you have only one master with a CA and it dies
and you
have no
backups then you are pretty much hosed at the moment.
IPA is so much more than just an LDIF.
_Could_ you use an LDIF to restore the data minus the
certs? Yeah,
probably, with a whole ton of work and expertise.
Would it
be worth the
trouble and would you ever fully trust that you
got it 100%
right?
The best solution is to maintain multiple masters
and > 1
CA. If one
dies then you delete it and provision a new
master. You can
maintain the
old name if you want.
Or if you use VMs you can use disk snapshots to
maintain
backups.
