Hate to impose, but how do you back up the "imported items" if you don't do it (check the box) in AC Backup?
I can probably find the file by looking around, but then it won't be encrypted, and doesn't seem like it will synchronize with the AC encrypted file.
I guess I'm actually pretty confused about how to do a backup if you don't just automatically back up everything and get AC to tie it all up in one .enc package.
You use a 3rd party program to back up the "import items" folder and do incremental (changes since the last backup) backups. Thus, after the first backup, it will only import the, say, 20 items that were imported the previous day, because the others are already in the backup.
Many backup programs will encrypt, especially those that sent it out to the web.
Some programs will allow you to "seed" the backup by moving a copy to the backup site and thus do not have a long mega-gigabyte initial backup.
Crashplan will allow you to backup to your own computers for FREE. You set it up on, perhaps a secure home computer and in the server and it will send the .enc file from the AC backups along with the import items incremental. It can be set up to run between midnight and 6 AM so it doesn't impinge on daytime internet traffic.
