Back In Time 2.0.0 Release Candidate 1

This is the first release candidate for Back In Time 2.0.0.

It is one of the largest updates in the project's history. It includes a major refactoring of the configuration mangement, a complete rewrite of the mount subsystem, replaces EncFS with Gocryptfs for encrypted profiles, and removes several deprecated features.

Although extensive testing has been performed, this is still a release candidate. We encourage users to test it
and report your tests even if you haven't found any regressions. Tests without regressions are also an important information to the project and its release process!

Warning

Do not test this release with your regular configuration.

Version 2.0.0 migrates the configuration and the changes might not be backward compatible. EncFS profiles are also removed. Once a configuration has been opened with 2.0.0, it may no longer work correctly with older Back In Time releases.

Please test in a virtual machine or with a separate configuration using the --config command-line option.

Highlights

• Complete rewrite of the mount subsystem (backend and encryption handling).
• Gocryptfs replaces EncFS for encrypted SSH profiles.
• Major refactoring of the configuratoin mangement.
• Calculate disk space savings because of hard-links.
• Numerous bug fixes, GUI improvements, internal cleanups and more refactoring.

Breaking Changes

• Python 3.13 or newer is now required.
• EncFS support has been removed. Existing EncFS profiles are no longer supported and will be removed.
• Config files written by 2.0.0 are not backward compatible to previous versions.
• Some (not all) deprecated CLI options and commands have been removed.

For the complete list of changes, see the changelog.

• Compare with the previous release: v1.6.1...v2.0.0-rc1
