This is a really odd one. All of a sudden incremental back-ups using Windows Server Backup are blowing out with '0x8078015b - The Specified Network Name is no longer available.' If I change it to full backup it works fine, but of course takes a long time to complete. Switch back to incremental and the same error after between 1 - 1.5 hours...
Any ideas why incremental would start doing this after running every day for years?
Generally a full backup takes 8-9 hours and incremental less than two
Thanks
