v0.7.0

Overview

This release introduces significant new features, fixes, and quality of life improvements. These include enhancements to the Difference Engine: support for multiple -s|--start-path arguments, cache fixes, better file type detection when not using --file-types, and improved move detection behaviour when multiple destinations exist, as well as support for plugin priorities in Manager and the in-tree plugins (for example, allowing the administrator to choose between lvm2-thin, and lvm2-cow snapshot providers where both can snapshot the same volume), better documentation for the Mount Manager in the User Guide, and a new, user-visible timeline categorization ("yearly", "monthly", "weekly", "daily", etc.) that is available for all snapshot sets. This release also includes a fix for the snapm / podman netns mount issue documented in earlier releases (#586) and stronger validation for schedule create name arguments (#906).

Users should upgrade to v0.7.0 as soon as possible to take advantage of these enhancements.

Notes

• It is now possible to specify the -s|--start path multiple times when invoking the snapset diff and snapset diffreport commands. This allows the user to compare multiple independent subtrees in a single diff operation.
• The path based file type detection has been improved to support more common file extensions, text and binary path locations, and categorisations.
• A new BINARY_LOG file type categorisation has been added to describe files such as wtmp, SAR logs, and the journal.
• Plugins now support a PluginPriority configuration that specifies a positive integer priority level. The plugin with the greatest priority is chosen when multiple plugins can snapshot the same device. This allows the user to prefer lvm2-cow snapshots over lvm2-thin where both are possible and will in future allow support for file system level snapshots (for example, Btrfs). Refer to snapm(8), and snapm-plugins.d(5) for further information on configuring plugin priorities.
• The Mount Manager is now described in the on-line and in-package User Guide.
• The Mount Manager now handles unmounting of duplicate /run/netns mounts via a targeted workaround.
• The timeline classification algorithm used by the Timeline garbage collection policy has been generalised and is now available for all snapshot sets via the "Categories" snapshot set property and "categories" report field.
• The static file type classifier now uses a broader set of rules for classifying likely text or binary content types.
• The tree output format of the snapset diff command now displays separate nodes for paths that have both been moved and modified (for example, a file that was backed up and then changed in-place).

v0.5.3

Overview

This is a maintenance release for snapm-0.5-stable that includes two bug fixes.

Full Changelog: v0.5.2...v0.5.3

v0.6.0

Overview

This release introduces significant new features and fixes, including the Mount Manager and the Difference Engine for efficiently computing changes between two snapshot sets, or the system root file system and a snapshot set. Fixes include Stratis plugin performance enhancements and bug fixes for lvm2 device callouts . Users should upgrade to v0.6.0 as soon as possible to take advantage of these enhancements.

Notes

• It is now possible to mount individual snapshot sets and interact with them using the snapset {mount,umount}, snapset exec, and snapset shell commands. Snapshot sets are mounted under /run/snapm/mounts.
• Comprehensive file system comparison is now available with the snapset diff and snapset diffreport commands. See snapm(8) and the user guide for more information.
• The snapm.fsdiff API is considered unstable and may be subject to change in a future release.
• The snapset diff --output-format=json JSON schema is also potentially subject to change and will be formalised in a future release.
• The snapset diff/snapset diffreport command syntax is stable but output and formatting may change in future releases.
• Future releases may include new content differs for specific file types and more comprehensive file type detection when libmagic is disabled.
• Generating content diffs of large file system trees with many content changes may consume large amounts of memory: snapm will refuse to diff trees if VmRSS exceeds 33% of system memory after walking the filesystem. Caching is disabled if VmRSS exceeds 60% of system memory after computing diffs.
