Backing up using external hard drive
I've been having nothing but intermittent problems trying to backup to a Maxtor 250GB external USB 2.0 hard drive. I'm using a Dell PowerEdge 2600 server and I installed a USB 2.0 card in a PCI slot.
The hard drive is recognized just fine by MS SBS 2003 operating system. I can read/write files just fine to the drive.
My first question is should I be using a Backup-to-DIsk folder or a Removable Backup-to-Disk folder?
I've tried both. I setup a backup job for a full backup to the correct backup-to-disk folder device last night and ran it manually. It backed up about 40 GB in a little more than an hour. Then, the regularly scheduled job ran at 11pm last night and did an append job. It got to 18% of the verify operation and 'got stuck'. I had to turn off the power to the external HD because nothing else on the server responded. I couldn't even use the Start menu until I turned off the HD. I also tried cancelling the job, and it got stuck at Cancel Pending. This appeared in the log:
Storage device "Nightly Backup" reported an error on a request to read data from media. Error reported: The system cannot find the file specified. The media operation was terminated by the user..
Now, I'm assuming this appeared in the log because we shut off the drive, which is fine.
However, when we came in this morning before all this happened, and looked at backup exec, we had to click OK on 12 separate 'overwriting media' messages, except that the job was set to append, and the job log shows from the beginning:
Media operation - append.
Software compression enabled.
I've already read the article describing how to create backup to disk folders and removable backup-to-disk folders, so please don't just send me these links. Please verify that I am using the correct settings and let me know how I can most efficiently troubleshoot this issue.
