I have a backup solution that has been working well. It is running on three servers in different geographic locations backing up to different Azure locations. On two of the volume of data being backed up has gone from 10s of Mb to about 1Gb. Now the backup solution is taking too long to run (> 12 hours) and then either failing with no error or with "An unexpected error occurred...0x07EF9)
What is the best way to start again with a new backup set to get them running again? I have tried re-registering the server and reducing the size of the backup set with no improvement.
Thanks
