I can't use it day to day because I misses file changes. Expiring a bunch of images into a synced folder the app puts them in a .tmp folder until done and then moves them out, the app can't move the files because they are accessed by sync so I'm less with bad files structures. Sync is a long way from a 1.0 product, oh wait its 1.4... I can see why beta was added back on in 1.4. Real Use: I have have a nightly backup 'synced' to our file server and off site backup. The whole backup is 10gb and it rotates. Ex. Backup3 is deleted, Backup2 moves to 3, 1 to 2 etc. However due to the inability of Sync to move files it ended up re-syncing 40gb every night causing time and extra network congestion.
