We bought a new Buffalo NAS and I am setting up Backup to Disk Folder option in order to backup Exchange Server with GRT. But every night the backup job keep deleting previous day's backup sets. I want to keep the data at least two months. The Buffalo has 6TB on it, I also set "Overwrite recycle media contain in the target media set before overwriting scratch media set" in the media management. That still doesn't work.
If I using my local server disk to backup it will hold as long as the disk has space left.
What else I can do to prevent data keep getting deleted? please help.
In order to best help you we'll need to know the exact model number of the Buffalo device you have, and any error messages you might be getting.
