Backup and Restore AiX

Backup - Restore

MKSYSB (for rootvg, OS):
(only for rootvg and only for mounted filesystems)
mksysb -i /testfs/mksysb.0725                  creates an installable image of the rootvg (from NIM it can be restored)

The restorevgfiles and listvgbackup -r commands perform identical operations and should be considered interchangeable

listvgbackup -f /mnt/aix11.mksysb -r /etc/resolv.conf    restores the file /etc/resolv.conf from the specified backup
------------------------------------------------

BACKUP - RESTORE (for filesystems):

find /bckfs -print | backup -i -f /dev/rmt0    backup all the files and subdirs
                                               find: genereates a list of all the files
                                               -i: files will be read from standard input

restore                                        extracts files from archives created with the backup command.

JFS2 snapshot:
creates a point in time image, it is very quick and very small

------------------------------------------------

SAVEVG - RESTVG (for volume groups):

savevg -f /bckfs/backup.0725 bckvg             backs up all files belonging to bckvg to the specified file
restvg -f /bckfs/backup.0725                   restores the vg and all the files what have been saved with savevg
                                               (it creates the vg, lv, fs...)

TAPE:

tctl                                           gives subcommand to tape (move forward/backward)
tcopy                                          copies magnetic tapes
