Hi,

make_tape_recovery is a complete process of making a tape bootable alongwith copying the files to the tape. It infact internally also uses make_sys_image to backup files to tape.


make_sys_image is the method for backing up only your files to tape or local directory or remote directory.

make_sys_image is one of the steps performed by make_tape_recovery.

Also the intention of ignite backup should be to only back up vg00 and other application tools shall be used for backing up other data.

HTH,
Devender

The make_tape_recovery tool creates a system recovery archive and stores the archive on a local tape. make_tape_recovery is capable of creating system recovery tapes for all DDS and DLT tape devices, with the ability to span multiple tapes.The archive created by
make_tape_recovery is specific to the system it was created for and its identity includes hostname, ip_address, networking information,etc.In the event of a root disk failure, the recovery archive can be installed via tape to restore the system.

The best use for make_sys_image is when you are cloning boxes... make_tape_recovery is best used for backup and recovery of individual systems... although it can be used for cloning as well, but you will have to modify host specific data, IP, hostname... etc..

Shalom Wang,

make_tape_recovery uses the utilty make_sys_image with a different option set to create the tape archive.

Run a make_tape_recovery

then:
ps -ef | grep make_sys_image

You will then see the options make_tape_recovery uses.

Your make_sys_iumage will make a tar file that is suitable for use as an Ignite Golden image. There may be a brief disruption of network services while this happens.
