Backing Up a System without a Local Tape Drive
An IRIS workstation with no tape drive is backed up across an XNS Ethernet
onto a tape loaded on another workstation. Both systems must have network
communication capabilities. The system with a tape drive must have a host
name, which is referred to in this description as hostA, and must be in multi-
user mode.
To back up a disk onto a tape installed in a remote workstation, follow the
procedure for backing up a system with a local tape drive, but use the
command lines below for steps 4 and 8. Replace rmt1 with rmt2, rmt3, or rmt4
depending on your backup device (see Table 4-1).
4. Back up the root file system:
Using tar:
tar caBf - . | xx hostA dd ibs=10k obs=200k of=/dev/rmt1
Using cpio:
cpio -oha . | xx hostA dd ibs=10k obs=250k of=/dev/rmt1
8. Back up the usr file system:
Using tar:
tar caBf - . | xx hostA dd ibs=10k obs=200k of=/dev/rmt1
Using cpio:
cpio -oha . | xx hostA dd ibs=10k obs=250k of=/dev/rmt1
