REAR is an utility to install on Linux server (package: rear). With this tool, you can backup your OS, and more…

Configure the client to be able to backup on a nfs server

[root@linux1 rear]# cat site.conf
OUTPUT=ISO
BACKUP=NETFS
BACKUP_URL="nfs://aixsrv1/export/rear/"
REAR_INITRD_COMPRESSION="lzma"
AUTOEXCLUDE_MULTIPATH=N
AUTOEXCLUDE_DISKS=Y

On AIX server (or linux), configure NFSv4 Ex:

[root@aixsrv1]/export/rear# cat /etc/exports
/export/rear -vers=3:4,rw,root=linux1:linux2:10.0.0.123

[root@aixsrv1]/export/rear# cat /root/scripts/rear.sh

#!/bin/ksh93
#set -x
