Makefile bail if $VOLATILE is not tmpfs, fixes graysky2#33 Nov 26, 2016


Anything-sync-daemon (asd) is a tiny pseudo-daemon designed to manage user defined dirs in tmpfs and to periodically sync back to the physical disc (HDD/SSD). This is accomplished via several bind mounting steps and an innovative use of rsync to maintain back-up and synchronization between the two. One of the major design goals of asd is a completely transparent user experience.

Installation from Source

To build from source, see the included INSTALL text document.

Installation from Distro Packages

  • logoArch: in the AUR.
  • logoChakra: in the CCR.


Users of versions older than v5.69 MUST stop asd before upgrading. Data loss can occur if you ignore this warning.

Arch Linux users do not need to worry about if asd is installed from the official PKGBUILD in the AUR. This contains a pre_upgrade scriptlet that will stop asd for you.

I cannot do this for Ubuntu users building this manually.

You have been warned.

You can’t perform that action at this time.
