 ====== Backup all linux servers on a central server ======
-REAR is an utility to install on Linux server (package: rear). With this tool, you can backup your OS, and more...
+Packages also available for linux x84_64, ppc64 and ppc64le
-Configure the client to be able to backup on a nfs server
+[[http://relax-and-recover.org/]]
-<cli prompt='#'>
-[root@linux1 rear]# cat site.conf
+REAR will generate a bootable iso file (minimum image <100M), to recover your system, and a compressed tar file containing all other data.
+First install rear and dependencies:
+<cli prompt='$'>
+[root@rhlab1 ~]$ yum -y install mkisofs genisoimage attr bind-utils rear
+</cli>
+Configure rear using a NFS v4 mount point on nfssrv:
+<cli prompt='$'>
+[root@rhlab1 ~]$ cat /etc/rear/local.conf
+# Default is to create Relax-and-Recover rescue media as ISO image
+# set OUTPUT to change that
+# set BACKUP to activate an automated (backup and) restore of your data
+# Possible configuration values can be found in /usr/share/rear/conf/default.conf
+#
+# This file (local.conf) is intended for manual configuration. For configuration
+# through packages and other automated means we recommend creating a new
+# file named site.conf next to this file and to leave the local.conf as it is.
+# Our packages will never ship with a site.conf.
 OUTPUT=ISO
 BACKUP=NETFS
-BACKUP_URL="nfs://aixsrv1/export/rear/"
+BACKUP_URL=nfs://nfssrv/export/backup/linux
-REAR_INITRD_COMPRESSION="lzma"

-AUTOEXCLUDE_MULTIPATH=N
+ONLY_INCLUDE_VG=( ca )
-AUTOEXCLUDE_DISKS=Y
+EXCLUDE_MOUNTPOINTS=( /data )
+BACKUP_PROG_EXCLUDE=( '/tmp/*' )
 </cli>
+Test a backup using validation on each step:
+<cli prompt='$'>
+[root@rhlab1 output]$ rear -v -d -S -c /etc/rear mkbackup
+Relax-and-Recover 1.17.2 / Git
+Using log file: /var/log/rear/rear-rhldapr1.log
+Press ENTER to include '/etc/rear/os.conf' ...
+Press ENTER to include '/usr/share/rear/conf/Linux-ppc64le.conf' ...
+Press ENTER to include '/usr/share/rear/conf/GNU/Linux.conf' ...
+Press ENTER to include '/etc/rear/local.conf' ...
+Press ENTER to include '/usr/share/rear/init/default/01_set_drlm_env.sh' ...
+....
+</cli>
+For production backup use, remove validation option and or verbose and debug:
+<cli prompt='$'>
+$ rear -v -d -c /etc/rear mkbackup
+</cli>
+Rear supports also most backup software like Bacula, TSM… A full sample config file is located in **/usr/share/rear/conf/default.conf**
+Sample config file using TSM (dsm.opt and dsm.sys must be register):
+<cli prompt='$'>
+[root@rhlab1 output]$ cat /etc/rear/local.conf
+OUTPUT=ISO
+#BACKUP=NETFS
+#BACKUP_URL=nfs://systemh/export/backup/linux
+#
+ONLY_INCLUDE_VG=( ca )
+EXCLUDE_MOUNTPOINTS=( /data )
+#
+BACKUP=TSM
+COPY_AS_IS_TSM=( /etc/adsm/TSM.PWD /opt/tivoli/tsm/client /usr/local/ibm/gsk8* )
+COPY_AS_IS_EXCLUDE_TSM=( )
+PROGS_TSM=(dsmc)
+# Should the result from mkrecover/backup saved via TSM
+TSM_RESULT_SAVE=y
+# TSM archive management class definition
+TSM_ARCHIVE_MGMT_CLASS=
+# if TSM server confirms the backup was successful (to preserve space on the local system)
+TSM_RM_ISOFILE=y
+# where to copy the resulting files to and save them with TSM
+TSM_RESULT_FILE_PATH=/opt/tivoli/tsm/rear
+</cli>
+To exclude specific folders or files add the following line into the config file
+<code>
+BACKUP_PROG_EXCLUDE=( ${BACKUP_PROG_EXCLUDE[@]} '/var/www/html/*' '/software/*' '/repo/*')
+</code>
 On AIX server (or linux), configure NFSv4
