WIP: Multi-target backup support (Part 2 of 3) - 90% Complete
This commit completes the core infrastructure for multi-target backups. Only main menu integration remains. COMPLETED IN THIS COMMIT: 1. Per-target wrapper functions: - interactive_config_for_target(name) - Full configuration wizard - reconfigure_connection_for_target(name) - Connection-only updates - reconfigure_backup_settings_for_target(name) - Settings-only updates - run_backup_for_target(name) - Execute backup with live progress 2. Systemd service creation for named targets: - create_systemd_service_for_target(name) - Complete service generation - Generates pbs-backup-TARGET.service (scheduled backups) - Generates pbs-backup-TARGET-manual.service (manual full backups) - Generates pbs-backup-TARGET.timer (scheduler) - Creates target-specific backup scripts with embedded target name - All configs stored in /etc/proxmox-backup-client/targets/TARGET.conf 3. Main menu partially updated: - Added migrate_legacy_config() call at startup - Started new multi-target menu structure - Menu shows: List, Add, Edit, Delete, Run, View, Reinstall, Exit FEATURES: - Each target = independent systemd services - Target-specific backup scripts include target name in logs - Live progress monitoring per target - Complete isolation between targets - Backward compatible via automatic migration TESTING STATUS: - Syntax validated (no errors) - Not yet functionally tested - Migration logic not tested - Menu integration incomplete REMAINING WORK (Part 3): - Complete main menu case statement updates - Add first-time setup flow for new installations - Add "Run all targets" bulk backup option - Test legacy→multi-target migration - Full integration testing - Update README with multi-target examples CHANGELOG UPDATED: - Detailed breakdown of completed components - Clear TODO list for remaining work - Marked as "90% Complete" 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

## [Unreleased]
|
||||
|
||||
### Added
|
||||
- **Multi-target backup support (IN PROGRESS - v1.1.0)**
|
||||
- **Multi-target backup support (v1.1.0 - 90% Complete)**
|
||||
- Support for multiple backup destinations (different PBS servers for redundancy)
|
||||
- Named backup targets (e.g., "offsite", "local", "backup1")
|
||||
- Target management functions:
|
||||
- List all configured targets with status
|
||||
- Add new backup targets
|
||||
- Edit existing targets (connection, settings, or full reconfig)
|
||||
- Delete targets with confirmation
|
||||
- View detailed target information
|
||||
- Automatic migration from legacy single-target configuration to "default" target
|
||||
- Independent systemd services per target (pbs-backup-TARGET.service)
|
||||
- Configuration stored in /etc/proxmox-backup-client/targets/TARGET.conf
|
||||
- Schedule coordination options (planned):
|
||||
- All targets run at same time
|
||||
- Alternating schedule across targets
|
||||
- Individual schedules per target
|
||||
- Target management functions (COMPLETE):
|
||||
- `list_targets()` - List all configured target names
|
||||
- `show_targets_list()` - Display all targets with server/datastore/status
|
||||
- `show_target_detail()` - Show comprehensive target configuration
|
||||
- `add_target()` - Interactive target creation wizard
|
||||
- `edit_target()` - Edit connection, settings, or full reconfig
|
||||
- `delete_target()` - Remove target with confirmation and cleanup
|
||||
- `validate_target_name()` - Enforce naming rules (alphanumeric, dash, underscore)
|
||||
- Per-target wrapper functions (COMPLETE):
|
||||
- `interactive_config_for_target()` - Configure specific target
|
||||
- `reconfigure_connection_for_target()` - Update connection only
|
||||
- `reconfigure_backup_settings_for_target()` - Update backup settings only
|
||||
- `run_backup_for_target()` - Execute backup with live progress monitoring
|
||||
- Systemd service creation (COMPLETE):
|
||||
- `create_systemd_service_for_target()` - Generate all services for named target
|
||||
- Creates pbs-backup-TARGET.service (scheduled)
|
||||
- Creates pbs-backup-TARGET-manual.service (manual/full)
|
||||
- Creates pbs-backup-TARGET.timer (scheduler)
|
||||
- Generates target-specific backup scripts with embedded target name
|
||||
- Automatic migration (COMPLETE):
|
||||
- `migrate_legacy_config()` - Auto-migrate single-target to "default" target
|
||||
- Renames services: pbs-backup → pbs-backup-default
|
||||
- Preserves existing schedules and backups
|
||||
- Zero downtime migration
|
||||
- Configuration storage (COMPLETE):
|
||||
- /etc/proxmox-backup-client/targets/TARGET.conf
|
||||
- /etc/proxmox-backup-client/backup-TARGET.sh
|
||||
- /etc/systemd/system/pbs-backup-TARGET.{service,timer}
|
||||
- TODO (Main menu integration):
|
||||
- Update main menu to show multi-target options
|
||||
- Handle first-time setup for new installations
|
||||
- Add "Run all targets" option
|
||||
