I use a filesystem backup utility. How does this affect my Adeona client state ( .cst ) file?
If your filesystem is backed up, then an old copy of your .cst file may be archived as part of the backup. If someone is able to obtain the backup, then they would be able to track the locations you visit after the backup was made. However, the privacy of locations you visited before the backup was made would not be compromised. Like all backup regimes, we recommend encrypting your backups.
