Snapshots are saved as files with the .tsv extension. For incremental backups, they are saved directly on the destination, otherwise they are saved in

~/Library/Group Containers/8L4NN3ZTVN.org.desairem.SyncTime/Library/Application Support/snapshots

where ~ is your user directory.

Hint: you can show the snapshots in the Finder by opening the File menu or main window context menu and, while pressing the Option key, selecting Show Snapshot in Finder.

Structure

A snapshot is structured as follows:

• The first line contains the names of the snapshotted file properties. The first property is the file name.
• The second line contains the name of the root directory.
• Each following line represents one snapshotted file and contains the properties named in the first line. The file name (the first property) is relative to the root directory (resulting in the name of the root directory to be empty). If a property isn’t available for the given file, it is left empty (e.g. the size for directories). For files contained in a directory, the line starts with a number of spaces equal to the depth relative to the root directory (which has depth 0).
