Corri: depends on the error message, and the type of file on which it is "bombing". Adobe apps have notorious file-locking issues, which cause the files to be left open even after the application is closed. The only way to get the computer to "let go" of the files is to re-boot the computer. Try doing the copy after a clean re-boot, before touching any of the apps...see if it makes a difference.
Others: I said, "forget the technicalities"...but you won't, so here goes: this "backup" method only requires the user to save their files to a specific folder. that's it. the app magically detects any changes to any of the files contained therein, and copies those changes over a secure, 128bit encrypted link to a server at my office, which in turn, is mirrored onto another device, and then, the server is backed up onto tape, and the tapes sent off-site to a secure location. "file>>save" (which, you have to do anyway) and your file is in 4 places. (or more, if you use it to sync corresponding directories on other workstations). USB or other external media is fine... Lou's "every 30 days" would be good, too, if you can remember to actually *do* it. (I wouldn't). Even if you do, when your house burns down, the disk will burn up with the computer.
This is not the problem. the problem involves using a web "portal"...a page on a server that gives you a view of stuff on the network, including this magic folder, so that you can see it from say...someone else's computer. If you use my login to access this page, you see more than the average user. and yes, I deal with users every day...they have their own logins which limit the damage that they can do. If they were to report to me that they had "crashed the entire network", I know that wouldn't be possible. But if you say it in reference to my login...I'm going to react in an alarmed fashion, because it IS possible.
