zrepl/zrepl v0.4.0 on GitHub

Please check https://zrepl.github.io/v0.4.0/changelog.html for a full list of changes.

Highlights

Support for zfs send / recv flags in the config (send: -wLcepbS , recv: -ox ). (docs).
Parallel replication is now configurable (docs)
New zrepl status UI:
- Interactive job selection.
- Interactively zrepl signal jobs.
- Filter filesystems in the job view by name.
- An approximation of the old UI is still included as –mode legacy but will be removed in a future release of zrepl.

Breaking Changes

This release does not contain breaking changes.
However, users who skipped the 0.3.1 update should make sure that their pruning grid config is correct.
A bugfix in 0.3.1 caused unexpected snapshot deletions for some users.

New Users

We provide two quick-start guides for different usage scenarios: server-to-server continuous backup, and workstation-to-external-disk backup.

We highly recommend studying the overview section of the configuration chapter to understand how zrepl replication works.

Platform Issues

There is a Go runtime bug on FreeBSD 12.2 and newer that manifests in Go runtime crashes and/or lock-ups of the zrepl daemon. zrepl has a tracking issue which contains the link to the Go upstream issue. A workaround is available. Note that this issue also occurs with zrepl 0.3 and many Go versions - it was not introduced by the changes in this release.

Donations

zrepl is a spare-time project but nonetheless requires significant development and maintenance effort.
Please consider donating to support future development. Thank you!
