This has been described by others, but I have not found a solution. I have 7 PCs backing up with TI 10 build 4942 , to a 500GB network drive. I use differential backups. I have setup Backup locations for each PC on the network drive, with a rule of saving 7 files. I scheduled daily backups using the correct backup locations (top of the list). The file names are generated automatically, as it should. After a couple of months I found the network drive completely full and backups stoped. The reason was that the limit rule was ignored and dozens of backup files were saved. I deleted all the files, recreated the backup locations and tasks, and started over. It works for a while, but at some poit, on ALL PCs, the limit rule is ignored. Is there a solution for this? Is this a bug in the software? Thanks for any help.
