I have been having trouble with automated backups to a dedicated USB drive. I'm using a 3TB USB destination drive, backing up nightly. Total data and system on the server is < 1GB. I'm using all the default settings. It was working for a year, but now, after about 23 copies, it fails with:
Windows Backup encountered an error when writing data to the backup target.
Detailed error: There is not enough space on the disk
I have been using WBADMIN to delete the oldest 5 or 6 backups so it can keep going again for a few days, but it'll fill up again and not overwrite.
What should I do? I'm OK with this simple backup program, when it works. But I'm about to have the non-profit I'm helping buy some commercial program.
BTW, I didn't find any relevant posts on this specific problem.
