My backups fail without any noticeable pattern - they'll be going fine for weeks, then start failing due to an I/O error. I'm using Backup Exec 8.6 with an HP Ultirium 215 external tape drive. I've had consultants look at it, HP replace the drive twice, replaced the SCSI card, and tried HP's drivers instead of Vertas'. I'm out of options. Restarting the server seems to do the trick, but not for long. Desperately seeking solution...
Here's the error, which begins to occur during the verification process, and then starts happening earlier and earlier until I'll have just a few megabytes backed-up before this dreaded failure:
Error reported:
The request could not be performed because of an I/O device error.
