Your folders, always up to date. In the background, without a subscription.

A source folder, a destination — external drive, network share, FTP server or S3 storage — and SyncMirror keeps the two identical, in real time, without you thinking about it. Nothing is deleted without a safety net.

What SyncMirror does

A task is a source, a destination and a mode. It takes care of the rest.

SyncMirror runs in the notification area, detects what changes and copies it. You work in your folders as usual.

Choosing a task's mode: mirror or two-way, each explained — Each mode explains what it does before you choose it.

Two modes

Mirror, or two-way — depending on what you want.

Mirror: the destination becomes an exact copy of the source. What disappears on one side disappears on the other — backing up a PC to a disk or a NAS.
Two-way: both sides converge. A file added or changed on one side reaches the other, whichever side you worked on — two PCs, one shared folder.
Several tasks at once, each with its own mode, destination and pace.

Setting up an S3 destination in SyncMirror, with the connection test button — Setting up an S3 destination, with a connection test before saving.

Destinations

A disk, a share, an FTP server, S3 storage: whichever destination you want.

Local and network: a folder, an external drive, a network share, an already synchronised cloud folder.
FTP, FTPS, SFTP: your web host or your server.
Any S3-compatible storage: Amazon S3, Wasabi, Backblaze B2, Scaleway, MinIO, iDrive e2.
A connection test before saving: you know right away whether the credentials work.

Real time

A saved file leaves a few seconds later.

Changes are detected on the fly, with no schedule to set.
A remote destination, which cannot report its own changes, is re-read at the interval you set.
A log says what was copied, when, and what caused trouble.

The safety net

Nothing is deleted without a safety net.

A dated recycle bin on the destination side: a deleted or replaced file goes there first, and you keep it 7, 15 or 30 days — or indefinitely.
Conflicts are reported rather than decided silently.
An unexpected mass deletion pauses the task and asks for your confirmation before going further — an unplugged disk does not empty your NAS.
