Our exchange server (2003) stores dismounted because the backups didn't run, and the log file drive reached it's capacity. To get the stores mounted, they moved several of the log files to an off line drive (several gigabytes). The stores remounted fine. However, when they tried to run a backup, the backup ran, but the log files weren't purged. THe app log gave an error stating that the log files could not be truncated.
Now when a backup is attempted, it fails, and gives an error that backup failed because there were missing or damaged log files.
We are in the midst of migrating to exchange online. We only need this server to last another month or two, but are nervous that it won't make it. If we increase the size of the log drive, and move the original log files back to the original folders, will the backup work?
