Syncovery for Apple Silicon Now Available

A native Syncovery version for Apple Silicon is now available as a separate download. This version has been compiled for the arm64 architecture and optimized for new Macs with the Apple M1 chip. It runs a bit faster than the Intel version on these Macs, but the Intel version is also very much usable.

The feature set and user interface is exactly the same, except that PascalScript is currently not supported on Apple Silicon. If PascalScript is needed, you can safely use the Intel version of Syncovery on the new Macs.

Syncovery has been available for arm64 on Linux for several years now, so that the transition on Mac was easy to complete. Syncovery will be released in separate versions for Intel and Apple Silicon for many years in the future. Intel Macs will not be disadvantaged in any way, in the foreseeable future.

The Apple M1 version is a separate download rather than a Universal Binary, because we want to save the download bandwidth and not use any unnecessary disk space on customer machines.

You can download Syncovery for Mac here.

Deleting Files Older Than X Days

You can automatically delete files based on certain criteria with Syncovery. A frequently requested functionality is to delete files from a folder which are older than X days.

To delete files, you need to set up a job (profile) and mirror an empty folder to the destination using Exact Mirror Mode. For example, you can use a File Age filter to delete files older than 14 days only. You need to use Advanced Mode in Syncovery to do this.

After setting the job up with the correct filters, you need to test it in Attended Mode. Run the job manually and look at the Sync Preview to make sure it works correctly and deletes the correct files only. Then you can give it a schedule.

If you have thoroughly verified that the profile works 100% correctly, and does not delete any files that you want to keep, then go to Safety->Unattended and allow 100% deletions (because 100% of the older files are deleted).

To enable these deletions to occur in unattended mode, you also need to add a switch to the INI file. Add the following line to the [Main] section of the Syncovery.ini file (on Windows) in order to enable 100% deletions:


Syncovery 9 Released for Windows

After many months of development and thorough testing, Syncovery 9 for Windows has finally been released!

This is a major breakthrough in several areas:

  • SFTP speeds have been dramatically increased. It can fully use your Internet bandwidth and reach upload transfer rates of over 100 MB/sec.

  • Jobs can run in “Background with Preview” by right-clicking or by choosing the running option from the Gears toolbar button menu. This is very useful.
  • The Sz format can now contain multiple files rather than just one, similar to zip.
  • Syncovery can now back up NTFS permissions and alternate data streams to cloud storage.
  • Support for high resolution monitors has been added.
  • You can choose a new windowless mode, where all information is shown in the main window (“Run profiles in main window”).
  • And much more!

See the complete list of Syncovery 9 new features here, or download Syncovery 9 for Windows.

Syncovery 9 is a free upgrade for all licenses ordered since January 2018. If your license is older, please order your Syncovery 9 upgrade soon. Many thanks!

We are now working on the Linux and Mac versions of Syncovery 9.

Our new forum is live (no joke)!

Our new forum is now live and ready for your questions under

After more than ten years of using an external forum hosted at backupcreations, we now have a new forum on our own server. While most of customer communication is expected to continue to use our ticket system via, we look forward to answer your questions on the forum as well.

Please go ahead and register! This is not an April Fool’s Day joke ;=)


Dramatically Increased SFTP Speed in Syncovery 9

Today, we released the first beta version of Syncovery 9 for Windows. It includes a new SFTP implementation based on Putty. We call it the TGPuttyLib, which is a DLL based on the psftp tool from PuTTY.

SFTP speeds have been dramatically increased. It can fully use your Internet bandwidth and reach upload transfer rates of over 100 MB/sec. Find out more about Syncovery 9 here.

In addition to improved speeds, TGPuttyLib can work with all private keys that you can use with PuTTY.

TGPuttyLib is open source and available to all interested software developers.

Amazon drive no longer supported

Unfortunately, Amazon drive has been reduced to Amazon Photos in August 2019, and all third party solutions have been locked out. Some developers got a notification from Amazon, but unfortunately the Syncovery team was taken completely by surprise when it stopped working on August 22nd, 2019.

Syncovery can no longer access Amazon drive in any way. The new Syncovery 8.43 will warn users about this new situation.

We recommend choosing a more professional storage solution such as from Microsoft, Backblaze, Box, Google Drive, DropBox, or others.

If you need to download files from your Amazon drive before canceling your subscription, we recommend using the Amazon Photos app. It seems to work better than Cloud Sync on a Synology NAS. Most importantly, the Photos App will be able to show the total file count and size relatively soon after starting the sync, and you will be able to guess how long the whole download will take. As opposed to Synology Cloud Sync, which will just run for days and you never know when it might complete.

Syncovery 8 Released

The Windows version of Syncovery 8 has been released today. Syncovery 8 is a major new version with numerous larger and smaller new features and improvements.

Syncovery 8 is a free upgrade for licenses ordered on or after August 1st, 2015. All registration codes generated since then still work with Syncovery 8.

These are the most notable bullet points:

  • New .sz file format – allows uploading compressed and encrypted files without local temp files
  • Adds native support for Google Cloud Storage (v8.05).
  • Adds support for PCloud (v8.06).
  • Fast block level copying with the new File System Monitoring service (Windows only)
  • PascalScript allows to customize job functionality and e-mail notifications.
  • Subfolder selection can now be set to automatically include future new files and folders.
  • SharePoint and OneDrive folder listing is now “changes” based.

Chaining Profiles (Running Profiles in Sequence)

There are several ways to run jobs one at a time.

Running profiles with the scheduler running one job at a time

One way to run jobs one after another is to use the Scheduler. Give them a scheduled time and leave a minute between each profile. On the Scheduler tab sheet, click on the Tools and Settings button and uncheck “Start Profiles In Parallel”. Alternatively, go to the Program Settings dialog, tab sheet Advanced, and specify 1 for Max. simultaneous jobs.

Running profiles via manual invocation

For manual runs, select the profiles in the Overview, right-click the selection and choose “Run in Unattended Mode”. This will run them one after another, as opposed to “Run in Background”.

If you need Syncovery to do other things while the jobs are running, you can open Syncovery a second time.

Chaining profiles directly

Another way is to chain profiles. As an “after” command line in “Execute before/after” you can put:
RUN PROFILE Profile Name

This will start the next profile when the first one has finished, and so forth. The problem is that the chaining is always done, so it may be a problem if there is an occasion where you want to run only one of the chained jobs.

Using the command line

Yet another way is to use the Syncovery command line and invoke your jobs from a batch file or script:
Syncovery Command Line

Windows 10: Syncovery Update Required

Syncovery Update Required

For continued compatibility with recent Windows 10 updates, please make sure you update Syncovery to version 7.98d at least.

It is recommended to update Syncovery before installing any further Windows updates.

Syncovery 7.98d includes an updated Syncovery VSS Service to fix a potential compatibility issue that could cause the upgrade installation to fail and/or get stuck in a reboot loop. Or Windows might just boot up with a blank screen, or show a spinning mouse cursor instead of a login screen.

This happened only on some systems, but to be safe, please update Syncovery.

If you already updated Windows, that’s fine. In that case please update Syncovery too to avoid any potential problems in the future.
