The package provided re-sync timer triggers once per hour. Tips and tricks Sync at more frequent intervals It will also provide useful information such as dir size, paths, and if any recovery snapshots have been created. Run asd parse to view what what asd will do/is doing based on the entries in /etc/asd.conf. The resync-timer is started automatically with asd.service so there is no need to manually start the timer. Additionally, a provided resync-timer will run an hourly resync from tmpfs back to the disk. WHATTOSYNC=('/var/lib/monitorix' '/srv/http' '/foo/bar') Also note that using a value of /dev/shm can cause problems with systemd's NAMESPACE spawning only when users enable the overlayfs option. If using bleachbit, do NOT invoke it with the -clean system.tmp switch or you will remove a key dot file (.foo) from /tmp that asd needs to keep track of sync status. Note: The default value of /tmp should work just fine for the VOLATILE setting. This is a difference of six orders of magnitude or 1,000,000 times faster. The access time of RAM is on the order of nanoseconds while the access time of physical discs is on the order of milliseconds. Since the sync target(s) is relocated into tmpfs (RAM disk), the corresponding onslaught of I/O associated with system usage of them is also redirected from the physical drive to RAM, thus reducing wear to the physical drive and also improving speed and responsiveness. The design goals and benefits of asd are: Additionally, asd features several crash recovery features. This is accomplished via a bind mounting step and an innovative use of rsync to maintain synchronization between a tmpfs copy and media-bound backups. Anything-sync-daemon (asd) is a tiny pseudo-daemon designed to manage user specified directories referred to as sync targets from here on out, in tmpfs and to periodically sync them back to the physical disc (HDD/SSD).
