Keeping USB Drive Awake for Backups
Posted on 2004-09-21
Not sure if this is the appropriate topic genre. My apologies if not.
Have a number of clients using external USB 2.0 hard drives for external backups. Each is using Stomp Software's "Backup MyPC" (formerly Backup Exec by Veritas). Backups scheduled to run to internal hard drives, tape, or CD-RW run fine - as scheduled, however, backups to the USB drives try to run (as evidenced in Scheduled Tasks) but don't actually follow through and complete. In one case, I've written a batch file to "tickle" the USB drive hourly by creating folders and copying a text file to each of these folders on the USB drive. That has helped but w/ inconsistant results. It doesn's seem to matter the USB standard on the PC (1.1 or 2.0). All of the USB drives are USB 2.0 but USB 1.1 compatible. Nor does it seem to matter if the USB drives are local or across a network. All of the OSs are WinXP Home or Pro. No other Scheduled Tasks are conflicting. The computers themselves are not going in to "hibernating" or "suspended" mode - nor are their system drives allowed to spin down. All OS updates have been applied (short of XP SP2).
Would be greatful for your feed back - recommendations.
