Linux Backup and Sync Software You Can Rely On

Whether for personal or business use, digitalization has become an integral part of daily life. Instant communication, digital photo galleries, video-on-demand services, and even company management through digital devices and software are now standard in many industries. This digital shift enhances collaboration, speeds up data analysis, and automates and standardizes processes. However, digital systems, including the Linux operating system, are not immune to errors like data loss. Therefore, regular backups should be routine for both private and company data. With Syncovery, a versatile backup and sync software, you can perform regular Linux backups intuitively, automatically, and flexibly.

Syncovery for Linux with Web GUI has been released for desktop Linux, servers and NAS devices with Intel, ARM and PowerPC processors.

Using the Web GUI

When you install a NAS, Debian or RPM package, the Web GUI should become available automatically.

If you choose the .tar.gz download, you can activate the web GUI by running these SyncoveryCL commands in a Terminal window:
./SyncoveryCL SET /WEBSERVER=localhost (to configure the web server)
./SyncoveryCL start (to start SyncoveryCL – the start command line parameter is recognized since v8.25)

Open the web GUI in a Browser window by entering: localhost:8999. Unless you are accessing the Web GUI from localhost, it will ask for username and password. The defaults are: user name = default, password = pass.

This is the complete command line to configure the web server:
SyncoveryCL SET /WEBSERVER=localhost /WEBUSER=username /WEBPASS=password /WEBPORT=port /WEBDOCSPATH=path_to_web_docs_folder

To turn the web server OFF (requires a restart if SyncoveryCL is already running):

The Web Docs Folder is called WebDocs and it is included in the tar.gz archive that you download from this page.

Additional Information

SyncoveryCL will create a .Syncovery folder for configuration, logs, and databases in the HOME folder. It depends on the HOME environment variable. You can also use SYNCOVERY_HOME, which takes precedence. HOME should not be /.

The documentation is currently being written. For a start, here are some example command lines to configure and run Syncovery:

Run a job without saving it to the configuration file:
SyncoveryCL RUN /LEFT="/home/tobias/Documents/" /RIGHT="/home/tobias/DocumentsCopy" /L2R

Add this same job to the configuration file:
SyncoveryCL ADD /NAME="LocalTest" /LEFT="/home/tobias/Documents/" /RIGHT="/home/tobias/DocumentsCopy" /L2R

Run an existing job:
SyncoveryCL /RUN="LocalTest"

Configure a scheduled job (every 30 minutes):
SyncoveryCL ADD /NAME="LocalTest" /LEFT="/home/tobias/Documents/" /RIGHT="/home/tobias/DocumentsCopy" /L2R /Sched /Rep /Days=0 /Mins=30

List Jobs in Config File:
SyncoveryCL /LIST

Disable a job:
SyncoveryCL CHANGE "SFTPTest" /Disabled

Enable a job:
SyncoveryCL CHANGE "SFTPTest" /Disabled=No

Show job configuration:
SyncoveryCL SHOW "SFTPTest"

The easiest way to get the command line with additional parameters is to create the job in the Windows or Mac version, and go to the Information tab sheet in the profile editor, where you will see the profile XML and command line.

Start the Scheduler (only necessary if you don’t use the Debian or RPM packages):
SyncoveryCL (runs in the foreground)
SyncoveryCL start (becomes a daemon – supported since v8.25)
SyncoveryCL & (runs in the background but not as a daemon)

Stop the Scheduler:

SyncoveryCL /STATUS
