- Hi!
-
- We have just bought a new WangDAT 3200 4mm tape drive with data compression.
- Any hints on what would be the best values for the different qualifiers to
- the BACKUP-command when writing to this drive? (when running "on-line"
- image-backups as well as Stand-Alone backups).
-
- I'm especially thinking of the /BLOCK_SIZE=n qualifier. Also, will the
- qualifier /MEDIA_FORMAT=[NO]COMPACTION have any effect on this drive?
-
- The drive supports the DDS-DC tape format and yields up to 8 GB of storage
- on 90 meter tapes.
-
- Our setup: MicroVAX 3400 running VMS V5.5, approx. 2.4 GB of diskspace on 5
- drives connected via SCSI and DSSI.
-
- The WangDAT is connected to our VAX via an Emulex UC08 SCSI-controller (ROM
- revision P). $ SHOW DEVICE/FULL MUB0: shows that VMS thinks the drive is a
- DEC TU81 drive.
-
- Experiences, anyone?
-
-
-
- Please reply via e-mail. Thanks!
-
