Network newbie in desperate need of help
Hello everyone,
My question is a bit hardware-ish.
I am running a Windows NT Server 4.0, with Arcserve 6.0 for NT as my backup software, using a Sony TSL 9000 8-tape Autoloader as my tape device.
Backups went well until about two weeks ago when almost every backup job (both incremental AND full) would either "fail" or get "cancelled". I would get all sorts of error codes, namely E6096, E3714.
Not only that, the backup transfer rate had gone down from 60-70MB/min normally, to about 10-15MB/min (it went as low as 2MB/min today!). It would back up only a few GBs of data then churn up these error codes,then cancel the jobs.
I rebooted the server, it didn't solve anything. I rebooted the tape drive, still no improvement.
I looked through Computer Associates' (vendors for Arcserve) online help, but suffice to say, that was as good as watching my clothes hang dry.
Almost lost, I contacted CA. They looked at my backup log and gave me a one sentence assistance;
"I think you need to fix the device problems." (some help, yah?)
Now doubly lost, I need some help in trying to pinpoint exactly what are the devices that I need to 'fix'. I think my server setup is pretty simple with one NT server holding a few drives of data, connected to the tape drive.
I am very new at the whole network thing, but this issue needs to be resolved as data backup is of utmost importance for my office. I am still in the process of learning, so please kindly offer some help.
I attached below part of the log that stated the more common errors in my backups.
