Why Upgrade to SyncBackPro or SyncBackSE V12?

SyncBack V12 is the biggest release in the history of SyncBack. Whether you are using SyncBackSE or SyncBackPro, V12 brings significant improvements to performance, security, usability, and cloud storage support. This article explains the key reasons to upgrade from V11 (or older) to V12, with separate sections highlighting what is new for each product.

Features in Both SyncBackSE and SyncBackPro V12

The following features are available in both SyncBackSE and SyncBackPro V12. If you are using either product on V11 or older, these are the improvements you will gain by upgrading.

Insider Access with Upgrade Assurance

Upgrade Assurance subscribers now get Insider Access, which lets you use features destined for the next major release before it ships. This gives you the benefits of both a perpetual license and a subscription at a fraction of the cost. If your Upgrade Assurance expires, you lose access to the Insider features, but when the next major version is released those features become a permanent part of it.

Intelligent Compression

V12 introduces Intelligent Compression, which lets you assign different compression levels based on file type. You can configure highly compressible file types (such as .TXT, .LOG, and .CSV) to use high compression, while already-compressed file types (such as .JPG, .MP4, and .ZIP) use low compression. The result is faster backups that still achieve good compression where it matters most.

Locked File Handling

V12 brings three improvements for locked files:

• Copy locked files without elevation: SyncBackPro and SyncBackSE can now copy locked files using the Volume Shadow Copy Service (VSS) even when running unelevated, by using the Scheduler Monitor service. You no longer need to choose between accessing mapped network drives and copying locked files.
• Advanced VSS options: New configuration options give you finer control over how volume snapshots are created.
• Smart pause-and-retry: If a file cannot be copied because it is temporarily locked, SyncBack will pause before automatically retrying, reducing unnecessary failures.

Parallel Chunked SFTP Transfers

SyncBackPro and SyncBackSE V12 can download and upload files in chunks in parallel over SFTP using Worker Threads. Instead of transferring a file as a single stream, V12 splits it into chunks that are transferred simultaneously. This can significantly improve transfer speeds, particularly for large files on high-bandwidth or high-latency connections.

TLS 1.3 for FTPS

V12 adds support for TLS 1.3 with the Eldos FTPS engine. TLS 1.3 is the latest version of the Transport Layer Security protocol, offering improved security and faster handshake times compared to TLS 1.2.

Encrypted Rapid Transfer

SyncBack Touch's Rapid Transfer mode delivers high-speed file transfers. Previously, enabling encryption required disabling Rapid Transfer. In V12, Rapid Transfer now supports encryption, so files transferred to and from SyncBack Touch devices can be both fast and encrypted in transit.

Smarter User Interface

V12 includes many user interface improvements that make day-to-day use more efficient:

• Zoom support throughout the interface.
• File preview in the File and Folder selection window and the Differences window.
• Quick search by typing filenames in the File and Folder selection window.
• Shared file selections between profiles, saving time when multiple profiles use similar file and folder choices.
• Custom profile text colours in the main window to visually distinguish profiles.
• Dark mode enhancements with optional colour images.
• Differences window improvements: reset display, filters, and column widths; change formatting with optional indentation; apply actions recursively to folders and their contents; export directly to clipboard.
• Run with prompting: change the source or destination path before running a profile.

Other Shared Improvements

V12 also includes the following improvements available in both products:

• Automatic volume relabeling: Relabel source or destination volumes on backup success or failure.
• Email intelligence: SyncBack will automatically resend an email without attachments if it detects the failure was caused by attachments being too large.
• Log file retention: Specify how many days of log files to keep, preventing log files from accumulating.
• New variables: Numerous new log counter variables (e.g. %LOGERRORSCNT%) and volume variables (%LABELVOL=?%, %SERIALVOL=?%, %LABELOFVOL=?%, %SERIALOFVOL=?%).
• Abort after errors: Automatically abort a profile after a specified number of errors.
• Retry file verification: Improved reliability for file verification.
• File size tolerance: Option to ignore file size differences below a specified threshold.
• Automatic variable restoration: When changing the source or destination path, SyncBack attempts to restore any variables that were previously used.
• Run a program when all profiles end: Execute a program after all profiles complete, in addition to the existing shutdown and exit options.
• Basic AUTH: Support for Basic AUTH (e.g. http://username:[email protected]/) for HTTP downloads and FTP HTTP downloads.
• Hundreds of additional improvements, bug fixes, translation updates, and help file expansions.

SyncBackPro-Only Features in V12

If you are using SyncBackPro, the following features are available in addition to all the shared improvements listed above.

AI-Powered Scripting

V12 introduces AI support for scripting. You can describe what you want a script to do in plain language and have AI help generate the script code. V12 also includes expanded script functions (such as EnableProfile, DisableProfile, and new logging functions) and a script converter utility to help migrate legacy VBScript scripts to Basic or Pascal.

Enhanced Cloud Storage

SyncBackPro V12 adds significant cloud storage enhancements:

• MEGA S4 support: A new cloud storage provider is supported.
• Azure cold restore options: Choose the rehydration target (hot, cold, or cool) with optional high priority. You can also skip retrieval from Azure archive or Glacier archive storage entirely to avoid unexpected costs.
• Delete excess native cloud versions: Manage version accumulation on Amazon S3 and Azure, complementing the existing support for Backblaze B2.
• Customizable block/part sizes: Tune multi-part upload and download block sizes for Azure, S3, B2, Rackspace, and Google Storage.
• Reduced memory usage: Downloading large files from Azure and Amazon S3 now uses significantly less memory.
• Faster Google Storage uploading.

Advanced Logging

SyncBackPro V12 supports advanced logging options, including the ability to log to an external logging system. This allows you to integrate SyncBack logging with centralized log management platforms, making it easier to monitor backup activity alongside other system events.

SBMS Remote Progress

With SBMS V3 and SyncBackPro V12, administrators can view remote profile progress in real-time using the SBMS Console. You can see the live progress of a running profile on a remote machine without needing to access the machine directly or wait for the profile to finish.

Infisical Secrets Manager

V12 adds support for Infisical, an open-source secrets management platform. Infisical can be self-hosted, giving organizations full control over where their secrets are stored. This joins the existing support for AWS Secrets Manager, Azure Key Vault, Google Cloud Secret Manager, HashiCorp Vault, and Windows Credential Manager.

Other SyncBackPro-Only Improvements

• "Not specified" ACL option for S3 and Google Storage, including when creating buckets.
• New script functions: RunFileCompareSameEx, EnableProfile, DisableProfile, logging functions, and many more.
