Help! How do I exclude an archive during a backup I have two pc's on the same network. I'll call them 'pc-a' and 'pc-b'. First, I successfully archived 'pc-a' disk to 'pc-b'. Second, I successfully archived 'pc-b' disk to 'pc-a'. However, upon further inspection, I discovered that the backup of 'pc-b' included the 'pc-a' archive. This is not necessary and increased the size of the backup and the amount of time it took to complete it. Under Tools... Settings...Copy and backup options... 'skip archive files in archive library' is checked. Also, when I clicked on 'Exclude from copy/backup', all three of the default categories are not checked. Do I need to check 'Auxiliary files' to exclude the archive? When I look in the archive folder, i see files that end in '.pbf' and '.pfm'. What are these files? Finally, when I ran the backups, 'Image splitting' was enabled by default. The maximum split size is set to 4000 MB. As a result, I have quite a few 'arc_...' files. I think this would be necessary if I was backing up to DVD, but if I am backing up to a network drive or USB external drive, is it still necessary or recommended? I am using Backup & Recovery 10.1 Free Edition Thank you.
