Dear friends, Can any one give a backup procedure (incremental) for Digital Alpha unix u.4f or suggest what command to use cpio / vdump with full options and the recovery procedure please. Any help would be highly appreciated. email: myolai@yahoo.com thanks in advance.

Use tar in single user mode, you can tar every from root, except "/proc".

the recovery procedure for digital unix 4.0f: example:restore the root_domain disklabel -rw -t advfs rzx RZXXX mkfdmn /dev/rzxa root_domain mkfset root_domain root mount -t advfs root_domain#root /mnt cd /mnt vrestore -xf /dev/rmt0h

you can try tar for backup : tar cvf /dev/rmt0h FILE

try : #vdump Of - /root | (cd /dev/rmt0H ; vrestore -xf -)

vdump is the best utility for taking backup with consistently,faster and taking increamental backup also. Steps to take vdump backup of a filesystem: 1) Boot in single user mode 2) vdump -uvf /dev/ Example "vdump -0uvf /dev/rmt0h /" for taking level full backup of root filesystem. no keys--- tar can be used for taking any particular directory only. no keys--- cpio can be used for taking any specific list of files.
