Re: Backup error, Harware, invalid drive

I am now running away from tapes and using US, firewire drives or
esata drives. SCSI tape drives are usually fairly reliable. I did have
one a few months ago where a bad scsi cable prevented the sata based
server from rebooting. I changed the scsi cable and the server
rebooted fine. I have heard other folks mention that quality scsi
cables are important. One guy I know really likes these guys for scsi
cables.

Thanks Jim,

My OS is windows server 2003 standard with sp2, not the SBS, I have cleaned
tape drive, used new tape and make sure the driver, firmware is latest, also
I have performed different hardware checks and ensure the hardware is fine,
the error still, on the other hand, if I backup to a file on c:, it works
fine. any idea?

There is an emasculated version of Windows Server 2003 which has just
10 user access. It is rare and you have to look hard to purchase it. I
think it has small business in it's name.

Clean the drive with a fresh cleaning tape? Maybe scsi problems?

The tape media I used was LTO3 which can backup up to 400/800, it was working
fine for few months and suddenlly got this error.

another question I want to asked is what is the different of Windows 2003
standard and Small business server 2003?

after backup job started about 15 minutes and backed up 25G data already.
error as below

I have used local administrator account, it should have full access to all
folders and files and the backup can be successful on a smaller amount of
data for example less than 20GB. but error happen on bigger amount backup
like 100GB.

This is usually indicative of full backup media. SBS backup does not cope
well with backups that need to span multiple backup media. Your ability to
backup lesser amounts support this theory.
