- Dear networkers,
-
- some weeks ago I had to compare VMBACKUP (Systems Center) and BARS/VM (IBM).
- VMBACKUP seems to me the better product (not only because its cheaper than
- BARS/VM) especialy if you want to save your data on tapes or cartridges.
- Here are some differences I was told:
-
-
- VMBackup ! BARS/VM
- -----------------------------------!-----------------------------------
- !
- only 1 service-machine ! at least 4 service-machines
- !
- communication via IUCV ! communication via VMCF (older method)
- !
- saves data corresponding to the ! saves data corresponding to a specified
- online-directory of CP ! directory-file on a minidisk
- !
- uses more than 1 tape-drive at a ! uses only 1 tape-drive
- moment (so called streaming) !
- !
- uses less work-space on DASD (not ! uses more work-space on DASD (depends
- depends on file-size) ! on file-size)
- !
- twin-copies possible (with read- ! twin copies impossible
- check) !
- !
- ----------------------------------------------------------------------
-

- Have a nice day and
