I need to backup and restore a raw partition to tape. The tape holds 525MB and the raw partition is 730MB. Will the following sequence backup and restore the raw partition?

backup

---

(Put in tape 1)

dd if=/dev/rdsk/c0t5d0s3 of=/dev/rmt/c0t3d0s0 bs=512k count=1000

(Put in tape 2)

dd if=/dev/rdsk/c0t5d0s3 of=/dev/rmt/c0t3d0s0 bs=512k skip=1000 count=1000

restore

---

(Put in tape 1)

dd if=/dev/rmt/c0t3d0s0 of=/dev/rdsk/c0t5d0s3 bs=512k count=1000

(Put in tape 2)

dd if=/dev/rmt/c0t3d0s0 of=/dev/rdsk/c0t5d0s3 bs=512k skip=1000 count=1000

Would this work? I doesn't look right.

How is anybody backing up and restoring from raw partitions? Received on Wed Jun 29 1994 - 19:07:58 CEST
