Profile-sync-daemon

Profile-sync-daemon (psd) is a tiny pseudo-daemon designed to manage your browser's profile in tmpfs and to periodically sync it back to your physical disc (HDD/SSD). This is accomplished via a symlinking step and an innovative use of rsync to maintain back-up and synchronization between the two. One of the major design goals of psd is a completely transparent user experience.

Good Advice

Always backup your browser profile(s) before using psd for the first time.

Users of eCryptFS

User of eCryptFS are encouraged not to use psd unless willing to help troubleshoot suspected browser corruption. See #158.
