elemental-lf/benji v0.3.0

on GitHub

Notable changes:

• Restores are now multi-threaded just like backups. This should speed things up quite a bit.

• Multi-threaded removal of blocks was implemented. This should speed up benji cleanup with B2. Due to a simplification in the code benji cleanup for S3 based storages is probably slower than before. Try increasing simultaneousRemovals in your configuration if you're affected by this. If this doesn't help, please open an issue.

• The backup scripts got another major overhaul:

  • It is now possible to hook into strategic points in the backup process with custom bash functions.
  • Prometheus metrics were reimplemented with these hooks and are now specific to the benji-k8s Docker image.
  • The foundations for freezing the filesystem before a Ceph snapshot were laid.
  • The scripts in the benji-k8s Docker image now generate Kubernetes events about backup failure or success. These events are attached to the affected PersistentVolumeClain and can for example be viewed with kubectl describe pvc.
  • benji-backup-pvc was renamed to benji-pvc-backup.
  • Support for the try/catch construct based on the bash-oo-framework was removed. It had limitations and was causing problems with certain IDEs.

• The default for simultaneous read and writes was increased from one to three to get better out-of-the-box performance. The default for the simultaneous removals was set to five.

• Left over locks due to power outages are similar events can now be overridden. This applies to benji rm and benji cleanup.

• A typo was fixed in the metadata-backup command. It is now correctly spelled metadata-backup and not netadata-backup as before. User action might be required if you're using this command in your scripts.

• A bug was fixed where blocks where not properly cleaned up when multiple storages were in use.

• The documentation was updated, but we're still not up-to-date at all fronts.
