On my laptop running Win XP Home Vers 2002 SP3 and on my desktop Windows 8 machine, I can not directly backup my BaseCamp data to a removable USB jump drive. The message I'm getting is "The Backup file 'K:\BaseCamp 2013-02-12.Backup' is invalid or read-only.
If I backup the BaseCamp data file to my Desktop instead, it works and I'm able to then copy the .backup file to my removable jump drive and then restore from it to either my laptop or home PC.
I wish to transfer my current BaseCamp data back and forth between my laptop so I can take it on the road with me when I go off-roading.
