Easy folder sync between Windows and Linux/Mac

Acrosync for Windows can sync entire folders with any Linux/Mac/NAS without installing server software. That is because it is the only native Windows implementation of rsync, a powerful folder sync tool that is ubiquitously installed by default in the non-Windows world.

Download

No more cygwin

Acrosync for Windows is not dependent on cygwin and it is very easy to install. Just download a small installer and a few clicks later you're ready to go. An ssh client is built-in, so there is no need to setup password-less login for rsync over ssh.

Moreover, not depending on cygwin also means that, had there been any issue, we can fix it and send you a new executable within 24 hours in most cases.

Dropbox replacement

Acrosync integrates a file system monitor that can detect file changes. Using the default backup mode, new or modified files will be automatically and almost instantly uploaded to the rsync server. File deletions can also be automatically propagated to the server if the 'propagate deletions' option is selected.

If you currently rely on Dropbox to automatically sync file changes from one computer to another, you should switch to Acrosync, which has no limits on storage and costs a low one-time license fee (after 15 day free fully functional trial).

Time Machine style backups

When this option is selected, Acrosync is capable of creating space-efficient incremental hourly backups on the server, taking advantage of the '--link-dest' option provided by rsync. This essentially turns any Mac/Linux/NAS into a Time Machine style backup server, without installing server software and at no extra cost.

Volume Shadow Copy

When run as administrator, Acrosync can invoke the Volume Shadow Copy service prior to opening files. This way, files locked by other processes can still be uploaded, guaranteeing consistent backups on the server.

Versatility

Acrosync can connect to almost any Linux computer even without server-side configuration. This includes not just desktops but also servers, such as VPS or dedicated servers. A remote access account provided by most companies and universities works too. Or even a small form factor computer like Raspberry Pi.

For Mac, the 'Remote Login' option in System Preferences should be enabled. For windows, cygwin is recommended and then openssh and rsync packages must be installed.

Sync with QNAP and Synology NAS boxes is official supported.

Acrosync can also sync with most rsync storage providers, such as rsync.net, HiDrive (paid accounts only), and Strongspace out of the box.

Flexible pricing

A commercial, perpetual Acrosync license costs USD $49.99 and can only installed on one computer. To encourage personal use, a special type of license for syncing and backing up non-commercial documents can be purchased at the same price but can be installed on up to 5 home computers.

In addition, to celebrate the launch of both Mac and Windows versions, we are offering a promotion code acrosync for a 40% off discount until Nov 30, 2014.
