We're really excited to announce the public beta of KeepVault v4.0 (contact us via our support site here to gain access to the beta)!
Version 4 of KeepVault Online Backup brings three important new features to the desktop and server software, and support for the latest iteration of Windows Home Server, Small Business Server, and Storage Server (the codename 'Colorado' series of servers). You can read about the server support in our last blog post here. We expect that KeepVault 4.0 will be finalized/ship in early April, once we've listened to and included feedback from the public beta.
The feature chart snippet below shows the features new to the software, namely:
- differential file backup
- file versioning
- 256 bit encryption

new features in KeepVault v4.0 Pro
Differential File Backup
Rather than backing-up the entire file every time it changes, file differentials only protect the portion of the file that has changed! This feature is especially important for large files or files that change frequently, as upload times will be reduced considerably. The result is that your data is protected faster, further reducing the chance of loss. Our innovative and proprietary approach to differentials automatically balances storage usage (having lots of differentials takes up more space that just having one master file), upload times, and periodic complete reupload of the file. Differential file backups are available to KeepVault Pro & Business users.
File Versioning
Released in conjunction with file differentials is KeepVault's new file versioning system. Working in parallel with file differentials, KeepVault Pro & Business allows users to restore point-in-time versions of changed files. File versions are also available via the Web Interface. Obviously as one stores more and more versions of files, so a user's storage account can quickly fill up. Thus, to alleviate the maintenance burden of managing/deleting multiple versions, KeepVault Pro & Business file versioning includes a clever automatic pruning system to balance space usage and version availability.
256-bit Encryption
Listening to customer requests we have increased the encryption level available to our KeepVault Pro & Business customers from 128-bit to 256-bit, helping to provide increased peace of mind about file security. Of course, all files are encrypted prior to sending over the Internet, and users retain the ability to use a default encryption key or set their own.
More to Come ...
We have some additional and important features in the pipeline that we'll announce shortly. Features that will provides advanced users with more control and configuration options, additional device support, and other enhancements that maintain KeepVault Online Backup as a leader in the space.
