+ No signup required
+ Don't have to pay for unneeded online storage as the sync is direct
+ No sync is too large or too expensive; whatever your upload link can handle
+ Writable and read-only folders supported
+ No arbitrary limits on folder count, location, naming etc
+ Easy to set up me-only folders, family folders, friends folders - flexible
+ Very clever when more than 2 devices present, as it's based on BitTorrent
- No signup means you manage your own settings. New device? Set up by hand.
- No online storage means both devices must be online at the same time
- Uses bittorrent protocol, so may be blocked or throttled
- Only has a concept of a folder, which is flexible but difficult to manage: no
centralized folder permission management to speak of; entirely manual.
+ Very simple to use
+ Great for sending someone a link to a file you have
+ Great for managing "best photos and videos" for your phone
+ Great for quick desktop access to snaps taken on the phone
+ Great for phone photo backup
- This is not really a "sync" product. It has other uses, but sucks for sync. If you
try to use it for sync, prepare for a world of hurt.
- Too simplified: can't even sync my D:\Photo folder; insists on it
being called D:\DropBox or D:\Photo\DropBox. And I have 5 others
I want synced.
+ Share with other registered users or just yourself
+ Access rights for other users: read-only or read-write
- No delta-sync. Contrary to what Syncplicity is trying to convince me of,
yes I DO need it. Every time I change an MP3 tag or an IPTC tag on a
few hundred files.
- Sometimes says things are synced when they aren't.
+ A bit more options in the UI
+ Delta sync
- Can't sync with other users; only with self, i.e. every PC has full
access to all shared folders.
+ Direct sync, without online storage
+ Sync over LAN while disconnected from the Internet
- Still in development, no public release available
? Try it for yourself, not much experience with this one.
+ Sync over LAN
- No conflict resolution; just overwrites old files.
- There were a few things I thought were too dumb in the UI.
- No support for folders; a single DropBox-style folder
- No sync with friends; they must use a browser
- No direct sync; everything must be stored on SkyDrive
+ Great for backups
- Sync feature is very primitive, not being the main feature. Only syncs
local HDD folders with the online disk.
None of these have:
- Any way to properly set up the initial sync on a mostly-synced PC. All of them will just mush the two together. There is no way to say "hey, this one is the proper copy and this one needs to be made the same".
- A powerful conflict resolution mechanism. I have to clean out duplicate crap files all the time.
- Full progress indication on the computer receiving files.
P.S. Please point out any mistakes and I'll correct them; I haven't used some of these as much as others.
Windows Live Mesh (going offline 13 Feb 2013)
+ Sync directly without paying for the intermediate data storage (finally!)
+ Delta sync
+ Sync with friends (no read-only though)
+ Simple UI
+ Good indication of what it's doing and which files are stuck (though still
not always, but the competition seems to think this is altogether irrelevant
to the user)
- Absolutely no way to sync hidden files or files with certain names
(thus cannot sync a Mercurial repository without breaking it)
- Arbitrary limitations on the number of folders (10), number of files per sync
- Online storage is fixed at 5GB, and can't be expanded even if you want to pay
