FINE TUNING TAPE FILES

RDX tape drives, by HP (tandenberg)
did you reload all that HP software and drivers fresh?
did you try fresh tape.
i replace the tape drive, (new , used, NOS , from whom, ebay)

i bet the tape drive, logs errors, if you look,
the driver software will log that, and you can see why the tape
failed, my guess, damage to the tape, end to end.
try fresh new tape, NEW in a box, not used.

Have you tried remaking the backup job? its a simple job action

LOoks to me like those files are either missing, OR the tape drive no longer recognizes the tapes

Try to use a cleaning cartridge. If the tape drive is still not recognizing the tape media after you clean it then your heads are bad

Your last print job might have crashed, but it's still trying to send data to the printer.
If you have a Windows system, Go to Printers from the Control Panel and double-click on the printer. If you see any print jobs listed, choose File/Cancel All Documents.

But sometimes that doesn't work - then follow these steps to get rid of all stuck print jobs:

1. Start –> Run Type “services.msc” without quotes
2. Find PrintSpooler and Stop the service
3. Navigate to C:WINDOWS\SYSTEM32\SPOOL\PRINTERS and delete all files in the folder.
4. Next Repeat Step 1 and Start the PrintSpooler Service.

Hope that helps - Sam

Hi,
The low throughput may be because of many factors. Check the below factors.. It could improve your throughput.
1. Restart and disable any antivirus firewall on both backup server and client. The network utilization should be more than 20% in the master backup server. Just to make sure there is no hinderence to data flow, try copying a single big file (a 1Gig ISO file will do) from any server to backup server, the network utilization should shoot above 10% then. And will vary to 20%. If it is steadt @ 8 or 10% then firewal is the culprit. Disable it.
2. Team 2 or 3 NICs in the master backup server. Teaming at the client will also help.
3. Check the total size of data to backup, and the average size and number of files to backup, if the average size is in the range of KBs and the number of files is very high. Then only the 'Flash Backup Liscence" will only help.
Please come back and post the ratings for my solution if it turn to be of any use to you. Thnx

start over process and dont cancel because the backup file is unique and this has several disks (if needed), and only all disks put togelher you can retrive data inside. like rar files, same principle.

Unfortunately, the data types you described are already compressed.
Your hardware and software cannot compress it any further. In fact, compressing compressed files actually increases the file sizes. Don't worry, Backup Exec knows better than to compress compressed files so you can leave your settings in place.

The compressed capacity of a tape drive is a marketing ploy by the tape backup industry to make them more appealing. Yes, if your backup consisted entirely of uncompressed files you might get close to 75GB but never 80GB. You can only count on getting the uncompressed capacity of a tape.

Three options:
Obviously, a higher capacity tape drive will resolve this problem.
You could also swtich to using two tapes but you would have to load the second tape when you arrive for work in the morning and your backup would have to finish during the business day.
Finally, if you have some data that does not change frequently you could seperate it from your active data. Backup the active data on your regular backup. Now you can backup the "archived" data manually with a separate backup job. Once backed up you only have to back it up again when new data is added to the archive.

I hope this helps.

I called the manufacturer and realized I was using the wrong type of recordable DVD disc to dub to. Non copy protected VHS tapes dub just fine as long as I'm using the proper disc.

This is from Xante's 3G Manual (downloadable via PDF)
"Printer Timeout The Timeout feature allows you to select the number of seconds the
printer waits for additional data before cancelling a job and returning
to the READY/IDLE state.
Set Timeout from the MISC:TIMEOUT configuration menu. The
factory default of 40 seconds (40 Sec) is an average setting. Set
timeout according to the type of files you send. Use a low setting for
small, simple files to prevent an indefinite tie-up on one job. Use the
300 or Never setting for large files, such as graphic intensive or CAD
(Computer Aided Design) files, to allow enough processing time.
With the NEVER selection, the printer does not timeout; it waits
until it receives additional data or until the printer is reset."

Bit of an odd one but i agree that block size could cause an issue.

Try this link for the HP tech manual for this drive.

It may help with your issue and does detail block size changes on some systems.
