SBS 2011 Backup Drive
We are having an issue where our backup drive is being overwritten after a few backups
The drive model is a Seagate 8Tb Backup Plus Hub (STEL8000200)
the drive formats ok to a 512Kb sectorsize

it overwrites , leaving no history on the drive , none of the partitions to be backed up are over 2 tb
Might the drive be low on space? If less than 15% free space, the "auto-delete" function will kick in and delete old backups. If it deletes an original backup and not an incremental, all files are deleted, as there is no "master" and it starts fresh.

Disk has pleanty of free space , we are getting this issue with 2 drives that are the same
What are you using as a backup program? I don't believe that Windows Server Backup for anything before Server 2012 will work with Advanced Format Drives, which would include anything over 2T.

You may also want to review the following regarding limits. SBS still cannot backup individual volumes greater than 2 TB in size:
