RsyncOSX

Caution: always verify, by a --dry-run, the result of a new task before executing it. See synchronize data task how to verify a task. A task require minimum a local catalog and a remote catalog. Continue to add new tasks until completed and tasks are saved to permanent storage after each entry. Select local catalog either by GUI, drag and drop or by enter text directly. Add is selected by choosing Add task on the sidebar menu.

There are three options for executing several synchronize tasks. The three toolbar buttons are: Search for all tasks with files to synchronize and execute. or by ⌘B shortcut Do an estimation run and present which tasks with files to be synchronized. or by ⌘T shortcut As above, but for the selected tasks. or by ⌘R shortcut A double click on a task executes an estimation run and shows the result of the estimation.

In Synchronize view tasks can be executed as single tasks. Execute single tasks require two double clicks: the first double click for estimation (--dry-run) and the second double click for executing the task The output from rsync is presented after each run. Verify and execute a single task Execute a single task is a two step operation. The first is an estimation or verify run, a --dry-run execution. The second one is the real run.

A restore of files should always be executed carefully. It is only allowed to do a restore of files to a temporary restore catalog. To set a temporary restore path select userconfiguration and set temporary path restore. There are two types of restore: full restore restore by files if the remote is a snapshot the list of files might be huge, depends upon how many snapshots and how many files in a snapshot A restore always start with selecting the task and then the Filelist button.

Utilizing snapshot is an effective method for restore of previous versions of data and deleted files. Snapshot utilize hardlinks and only changed and deleted files are saved as separate files in a snapshot. Files which are not changed are hardlinks to the original file. If a file.txt is saved in snapshot number one and never changed or deleted, the file file.txt in the latest snapshot is just a hardlink to the original file.

The verify of synchronized data is triggered by the File -> Check synchronized menu or the ⌘K shortcut. The --archive parameter is the normal parameter to use in synchronize and snapshot tasks because it is fast. The --archive parameter to rsync preserves a lot of attributes of files when synchronizing. Files transferred in –archive mode ensures that symbolic links, devices, permissions, ownerships, modification times, ACLs, and extended attributes are preserved. When synchronizing files based upon the –archive parameter, rsync compares file size and last modification time to compute which files to be synchronized.
