UNISON FILE SYNCHRONIZATION ARCHIVE
Topology is that it eliminates the possibility of confusing “spuriousĬonflicts” arising from the fact that a separate archive is maintainedīy Unison for every pair of hosts that it synchronizes.īut i didn't find any working example where more than 3 pcs making syncing. It allows two replicas of a collection of files to be stored on different hosts (or different disks on the same host. Organize the machines into a “star topology,” with one machineĭesignated as the “hub” and the rest as “spokes,” and with each spoke Unison is a file-sync tool for OSX, Unix, and Windows. If you need to do this, the most reliable way to set things up is to To keep larger groups of machines in sync by performing multiple Using Unison to Synchronize More Than Two Machines Unison is designedįor synchronizing pairs of replicas. And found that it works perfect for 2 computers and how about 3 or more ? I tried to specify 3 roots in confg file but it does not work in such way and expects only 2 roots.

if file changed on one pc others reflect this change as well. Ignore = Path Library/Application Support/Unison/unison.I need to sync 3 computers between each other in same way as Dropbox does e.g. Ignore = Path Library/Temperature/5-tmp-day.log My current setup sync my whole iPhoto Library (120Gb) and my iTunes library (100 GB). If you edit the same file on multiple computers a conflict will arise and an overreide direction can be specificed i.e. Ignore = Path Library/Temperature/0-min.log After this you just need to sync each time you switch computer i.e. Ignore = Path Library/Temperature/current-outside.txt Ignore = Path Library/Application Support/Unison/common Ignore = Path Library/Application Support/Unison/unison.db Ignore = Path Library/Application Support/Unison/fp* Ignore = Path Library/Application Support/Unison/ar* Ignore = Path Documents/Microsoft User Data Path = Library/Application Support/myTracks Path = Library/Application Support/Unison For example when I upgraded all my iPhoto thumbnails for the retina display of my new laptop this was just as few GB of syncing. Unless I edit/add lots of pictures then syncing only takes afew minutes.

Thus if B is the central device full synchronisation is achieved by a sequential sync:Īfter this you just need to sync each time you switch computer i.e. Syncing of more than two devices us undertaken by syncing to one central device sync. This allows specific sync profiles to be initiated by scripts or by cron.
be a client not a server, and tunnel everything else.įinally although the GUI is nice for monitoring, resolving conflicts or forcing overwrites the CLI can easily handle simple synchronisation sinarions, and has options for automated conflict resolution. This is also a good way to sync data off accounts with restricted permissions as you all you need to do be able to do is initialise an ssh connection i.e.

Install the client, on windows or linux and happily sync all data. This also opens up possibilities beyond the LAN to secure syncing over the internet via NAT.įinally, although here I discuss a homogenous all mac LAN Unison is cross platform.
UNISON FILE SYNCHRONIZATION PASSWORD
The other advantage is syncing is done over SSH, so if you setup public key authentication then only one port and no password is needed. For example, do you really need to sync all your old university files which you don’t change them very often any more? This makes scanning quicker. Similarly you can split your synchronisation into parts via different profiles so not all files are synced all the time. This allows Unison to sync it’s own configurations, which is very useful as an identical sync set can be initiated from either side. This means that bi-directioal syncing is possible with the same configuration file. local > remote or remote > local.Īnother advantage of the way you configure Unison is that server information i.e root sync directories of local and remote hosts can defined in a separate file to the paths to be synced or ignored.
Conflict resolution is handled well with the user able to override suggestions by skipping or forcing a specific direction of sync i.e. Unison works a bit like rsync in that although initial sync may take a long time afterwards only differences are transfered. I have been using Unison for over seven years and it’s great.
Currently I use Unison over SSH to sync my documents and some specific system files.
