- We have some old sets of backup (in 1/4-inch cartridge tapes) that I
- would like to convert to DDS (DAT) tapes.
-
- We need to do that for two main reasons:
- - We need to get rid of the cartridge autochanger.
- - One DAT tape is much smaller and easier to store than sets of 8
- cartridge tapes.
-
- Could somebody please give me a light on this problem? Please ...
- THANKS in advance for any hints and have all a great 1993,

- A description follows:
- Hardware (HP9000-835, HP-UX 8.0):
- ========
-
- FROM:
- ----
- The old backups are store in sets of 8 cartridges. The device used was
- the HP 35401A ( 1/4-inch Cartridge Autochanger Tape Subsystem).
-
- TO:
- --
- The new backups will be stored on DDS (DAT) tapes, and the device to
- be used is a HP 6400-1300s drive
- (1.3 GByte DAT drive).
-
- Backup PROCEDURE:
- ================
-
- The following procedure was used with the cartridges for backup:
-
- /etc/fbackup -I /usr/adm/fbackupfiles/system.log -0uf - -g
- /users/root/backups/systemgraph | compress | tcio -oV -S 8 -l 1
-
- /dev/rct/c5d0s2
-
- The retrieval process is the following:
-
- tcio -i -l 1 -n 8 /dev/rct/c5d0s2 | uncompress | frecover -xf - -i
- FILENAME(s)
-
- PROPOSED SOLUTION (which did NOT work):
- ================= ------------------
-
- Extract the whole compressed backup and re-direct it to the DAT drive
- (/dev/rmt/0m):
-
- tcio -i -l 1 -n 8 /dev/rct/c5d0s2 > /dev/rmt/0m
-
