Stairway to backup - Stairway's end

This is a maintenance release for NPBackup v3.
So far, v3.0.3 has been a pretty solid release, so this is a fairly small release.
We're also heading for a GUI rewrite currently, but that shall become v3.1.

3.0.4

Disruptive changes

• compression option is decided at repo level, so it was moved to repo_opts section
  • The configuration files will be automatically migrated on first run
• This is the last version to support deprecated parameters ---check, --repair- and --prune-max
  • They have been replaced by --check, --repair and --prune with additional parameters to fine tune the operations

Features

• pack_size option has been added to backup_opts section, allowing to set restic pack size for finer grained deduplication

Fixes

• Compression value was not honored on init command
• CLI: --force switch now bypasses random delay before backup
• CLI: Fix --dump command that tried to interpret output as strings, also make it faster by changing polling method
• CLI: Fix stdin encoding issues

Disruptive changes

• An automatic config file migration tool has been added which will migrate config files from 3.0.0 to 3.0.3

Stairway to backup - stairway maintenance

Maintenance release

So this is shall become the first maintenance release for v3.0.0 series.
At this point we shouldn't add any major features, but still add minor enhancements.
The major enhancement here comes from random housekeeping / auto-upgrade run chances, which will allow many workstation instances to spread these actions over a larger time range, in order to avoid network congestion.

Enhancements

• Enable prune tuning parameters
• Add housekeeping after backup run chance parameter
• Add auto upgrade run chance parameter
• Configuration file checks are now subversion aware
• Allow partial configuration files (missing default repo / group)

Fixes

• Missing specified backup paths won't trigger errors (backend behavior), see #151
• Updated Grafana Dashboard: fixed variable gathering from wrong metric name)
• CLI: Fix --prune-max (deprecated)
• CLI: Add --prune max (replaces --prune-max)
• CLI: Fix --policy not allowed in group operations
• GUI: Fix CTRL+C triggers and error, #125
• GUI: Fix showing inheritance icon on entries wiith units, #148
• GUI: Permission set button should be red if no permission set
• GUI: Default units should be IEC bytes, like restic backend, fixes #143
• Fix for textcollector & push gateway data being overwritten in group operations mode, #150
• Dissociate minimum backup size error from absent backup error, #141

Misc

• GUI general UX and cosmetic changes

Thanks to @GuitarBilly for his help reporting bugs ;)

Stairway to Backup

Official v3.0.0 release

It's been a long wait for this release. Almost all parts of NPBackup have been rewritten or have been updated.
A very long release candidate period has been observed in order to iron out all possible bugs and nipticks.
So here we are, proud to build some stairways to h... euhh easier but reliable backups.

This release is way too big to enumerate all the new functions. But here's a list of the major features:

• Multi-repository support
• Easier repo setups which can inherit from group settings
• New viewer application for viewing/restoring data from any restic repositories
• CLI and GUI are now two separate applications (still GUI can act as CLI)
• CLI can now fully operate in API mode via --json parameter
• New operation center which allows to run operations on multiple repositories and / or groups
• New housekeeping operation, which checks, implements retention policy and prunes backups
• Prometheus monitoring now supports all operations
• Upgrade server can now filter on client / group / platforms
• Memory and speed optimization
• Automatic tests

For the full changelog, please see CHANGELOG.md file.

Special thanks to @GuitarBilly for his help in finding bugs / asking questions / general help.
