Adam,

As long as your DVD-RAM disk appears to Windows, it should appear to
Retrospect. The only exception that I can think of off the top of my head is
if the drive is assigned letter A: or B:. If so, Retrospect will not
recognize it. Change its drive letter.

As far as your DAT drive, tape capacity is dictated by several factors, none
of which involve software settings or anything you can set as options. Tape
drives are streaming mechanisms, meaning that tapes move at a constant speed
during backups and do not wait for data to arrive to them. As such, transfer
speeds, whether you're doing local or network backups, and problems with
your hardware can all affect the capacity you get per tape.

You also might want to check out Dantz Technical Note 305, at

This note, "Streaming Tape Capacities Explained," should go into more detail
on the possibilities for tapes filling up sooner than expected.

As always, call us for further help.

I just purchased the server version after having much grief with Veritas
Backup Exec and have a few problems.

 

I called Dantz before buying the product and they said yes to the 9210 being
supported however when the media is in the drive it does not show up on the
list.  The device area in Retrospect shows there is not a driver available
for the 9210 or the DVD drive or even the zip.  I do have media in the
drives.  What might I be doing wrong.

 

When doing a backup with a DDS3 tape it should handle 12 gig uncompressed or
24 gig compressed.  When it gets to 12 Retrospect is asking for another
tape.  I even tried to select choices for software compression but since
drive has hardware Retrospect will use that.  The manual says that if the
drive says DC it supports Hardware Compression.  The attached image shows
the properties of the drive. Ideas??  I have dried several DDS3 tapes.  I
have also erased tapes several times.  Format choices is not available.

 

System Properties 

Windows 2000 Server RC 2 Build 2128

Micron PIII 600 

320 Meg Ram 

2 9 gig LVD SCSI Hard drives

HP 9210 CDR 

Hitachi DVD Ram drive

HP 40i DDS4 tape drive

Internal Zip Atapi 

Adaptec 2940u2 LVD controller card

 

The hard drives and the 40i are on the same SCSI chain with active
termination set and hooked onto the 68 pin LVD connector on the SCSI card.
The CDrom and the CDR and are on another chain hooked into the 50 pin
connector on the 2940 Adaptec card.

 

Thanks in advance, 

Adam
