Starting from version 2.1, multiple versions of a file can be created on the Syncrify Server. Consider the
A user creates a new document and backs it up to the Syncrify
Later, the user makes changes to this document and backs up the modified version
of the same file
The Syncrify server will keep both versions of the file. The latest version
is stored as-is on the server but older versions just contain the difference in the file. If a
user decides to restore an older version, Syncrify server will rebuild the file on-demand.
Watch a short video demonstrating versioning in action.
Benefits of using versioning
Users can restore a previous version of a file.
Previous versions of a file are
stored in a special format containing enough information to rebuild the file on demand,
tremendously reducing disk space on the server.
Steps to use versioning
Versioning can be enabled or disabled on a per-user basis.
When creating a new user, the administrator must decide the number of versions to
maintain for every file. Specify a number greater than 0 to enable versioning. Assume a
backup is run every night. Specifying a value 7 for this field will create up to 7
versions of a file, each representing one day of data.
On the client's end, versioning can be further narrowed down to a profile level. This means
you can select the profiles for which versioning is enabled. This allows users to create versions for certain types of files but not others.
Follow the steps below to enable versioning on the client's end
Start Syncrify client
Select a desired profile
Click on the advanced tab
Check Enable versioning
Save the profile
It is important to note that previous file versions are automatically deleted when:
File encryption is enabled or disabled
Encryption password is modified
Versioning is enabled but client runs a backup job with this option disabled.
In this case, previous versions will be removed and new versions will be created
when it is enabled again.
The option "Delete files from server" is checked
and user deletes a file from the client machine.
Restoring previous versions (Using web interface)
Log in to the web interface using your login ID/password (this must be a non-admin account)
Navigate to the desired file. Click the right mouse button and select Previous Versions
Select the desired version from the list and download.
