NTBackup fails with "The requested media failed to mount. The operation was aborted."

I'm running SBS2003 on a HP ML350 G4P with a HP storage works ultrium 448 tape drive and using HP ultrium 2 tapes but keep getting errors when using NTBackup. I've managed to sort out the scheduling (well think I have) but for some reason keep getting 'the requested media failed to mount' error.

Here's the backup log file.

Here's details of the .bks file I'm scheduling:

C:\
C:\RECYCLER\ /Exclude
G:\
G:\DATA\TAS Books 3 Backup versions\ /Exclude
G:\DATA\TAS Books 3 Fix Btrieve\ /Exclude
G:\DATA\TAS Payroll Manager Backups\ /Exclude
G:\DATA\TAS Payroll Manager Testing\ /Exclude
G:\DATA\TAS Payroll Updates\ /Exclude
G:\DATA\TAS Books 3 updates\ /Exclude

G:\DATA\TAS Books 3 Companies not used\
G:\DATA\TAS Payroll Manager Companies not used\
H:\
H:\Users Shared Folders\ /Exclude
JET BIGBERTHA605\Microsoft Information Store\First Storage Group\
SystemState

And here's the scheduled script details:

C:\WINDOWS\system32\ntbackup.exe backup "@C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data\Daily Backup.bks" /n "Daily Backup" /d "Daily Backup" /v:yes /r:no /rs:no /hc:on /m normal /j "Daily Backup" /l:s /p "LTO Ultrium" /um

Any clues as to what is happening and what I'm doing wrong?

Also is there a way to add the date, time and possible day of the week to the media name once complete else they all end up being called 'Daily Backup - 1'?

Thanks in advance

hi,

what is the capacity of the tape you are using for the backups and how old are these tapes. From the log pasted it shows that i has backed up around 120 GB of data.  please verify the size of the data that you are backing up and also verify if that would fit in a single tape.

the backup failed because it was looking for a second free tape and could not find it. Hence failed.

pls update us the requested info so as to be of help

I'm using HP Ultrium LTO2 tapes which have a capacity of 400gb (although I don't expect to achieve this) which are all roughly 6-8 months old. Total amount of data to be backed up equates to around 360gb give or take the odd gb.

My calculations going by the log i posted indicate that it gets to 347gb before failing unless my long division is wrong...

ok tell me if this is 400/800 or 200/400. if it is 200 native 400 compressed then i think the hardware compression is working fine. only you need to either exclude certain folders or make a second tape available.

if the tapes 400 native 800 compressed then maybe somewhere either the tape drive is not able to write do to hardware errors or tape errors. try using a new tape if available and verify

The tapes are all HP C7972A which are 200gb native and 400gb compressed so I think from what you say hardware compression is working just that I need to exclude some folders / files to ensure it fits on the one tape as the server is unattended so changing tapes at 5am isn't feasible. Many thanks.

All I need now is to work out how to add the date, time and day of the week (pref) to the media / tape name so that they don't all appear the same in the media library.
