elemental-lf/benji v0.5.0

on GitHub

Notable changes:

• Added fsfreeze support to the benji-k8s Docker image. Just add the benji-backup.me/fsfreeze: yes annotation to the PVC. Kubernetes hosts are accessed via pods which are deployed by a DaemonSet, see the Helm chart for details.

• Use bulk inserts to speed up backups of images based on a previous version. This also decreases memory usage.

• Switched from in-memory block lists to an iterator based approach. This will increase performance and decrease memory usage when backing up large images.

• Fixed a wrong index on the blocks table. This should also increase performance. The database will need to be migrated with benji database-migrate.

• Laid the foundation for structured logging.

• Removed database table stats and assorted code and commands. Statistics are now kept together with the other version metadata in the versions table. This means they are also removed when the version is removed. If you want to keep historic statistics you need to export them beforehand with benji -m ls or benji metadata-export. This is a breaking change and you might need to adjust your scripts. As statistics are now included in a version's metadata the metadata version has changed to 1.1.0. Old metadata backups and exports with a metadata version of 1.0.0 can be imported by the current version. The statistics will be empty in that case. The database will need to be migrated with benji database-migrate.

• Fixed a bug in the time calculation of benji enforce which could lead to a late expiration of versions, the timing was a few hours off.

I'd like to thank @olifre and @adambmedent for their testing efforts!
