Clean old backups: `proxmox-backup-client prune` +2. Run garbage collection on PBS +3. Add more storage to PBS +4. Switch to file-level only or increase prune frequency + +--- + +## FAQ + +**Q: Can I backup just one partition instead of entire disk?** +A: Yes! During setup, specify `/dev/sda1` instead of `/dev/sda`. However, you won't be able to directly boot this as a VM without manual partition table recreation. + +**Q: Will hybrid backup run two backups simultaneously?** +A: No. On Sundays, it runs file backup first, then block backup. They're sequential. + +**Q: Can I change the weekly block backup day from Sunday?** +A: Yes! Edit `/etc/proxmox-backup-client/backup.sh` and change `[ "$(date +%u)" -eq 7 ]` to different day (1=Monday, 7=Sunday). + +**Q: Does block device backup require downtime?** +A: No, but it's a "hot backup" of a running system, so minor inconsistencies possible. For critical systems, consider backing up while system is idle or from Live USB. + +**Q: Can I restore a block backup to smaller disk?** +A: No, target must be >= original size. You CAN restore file-level backups to any size disk. + +**Q: Do I need encryption for block device backups?** +A: YES! Block device backups contain everything including swap (which may have passwords/keys). Always enable encryption. + +--- + +## Quick Command Reference + +```bash +# List all backups +proxmox-backup-client snapshot list + +# Restore file-level backup +proxmox-backup-client restore host/laptop/DATE root.pxar /restore/path + +# Restore block device to disk +proxmox-backup-client restore host/laptop/DATE sda.img /dev/sdX + +# Restore block device to VM disk +proxmox-backup-client restore host/laptop/DATE sda.img /dev/pve/vm-ID-disk-0 + +# Mount backup for browsing (file-level only) +proxmox-backup-client mount host/laptop/DATE root.pxar /mnt + +# Check backup size +proxmox-backup-client snapshot list --output-format json | jq + +# Manual block device backup +proxmox-backup-client backup sda.img:/dev/sda +``` diff --git a/CHANGELOG.md b/CHANGELOG.md index 5cb9eb3..4447ab8 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -8,6 +8,21 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 ## [Unreleased] ### Added +- **Docker-based cross-platform solution (v1.2.0 - NEW!)** + - Full Docker implementation for Windows, macOS, and Linux + - Dockerfile with PBS client in Debian container + - Platform-specific docker-compose files (linux/windows/macos) + - Daemon mode with internal cron scheduler + - One-shot backup mode for manual runs + - REST API server for remote management (optional) + - Health monitoring and status endpoints + - Automatic encryption key generation and management + - Build and deployment scripts (`build.sh`, `deploy.sh`) + - Complete Docker documentation (README-DOCKER.md, QUICKSTART-DOCKER.md) + - Organized in `docker/` subdirectory + - Cross-platform backup support matrix in README + - Platform-specific exclusion patterns + - Metadata change detection for fast incrementals - **Multi-target backup support (v1.1.0 - COMPLETE)** - Support for multiple backup destinations (different PBS servers for redundancy) - Named backup targets (e.g., "offsite", "local", "backup1") diff --git a/README.md b/README.md index 0ca8270..e0ee954 100644 --- a/README.md +++ b/README.md @@ -1,10 +1,12 @@ # PBSClientTool -Interactive tool for installing and managing Proxmox Backup Client on Ubuntu, Debian, and Arch Linux. +Interactive tool for installing and managing Proxmox Backup Client on **all platforms**: Linux (native), Windows, and macOS (Docker). + screenshot-2025-11-02_18-48-02 ## Features +- **Cross-platform support** - Native Linux + Docker for Windows/Mac - **Multi-target backups** - Backup to multiple PBS servers for redundancy - **Auto-detection** - Automatically detects your Linux distribution - **File & block device backups** - Supports .pxar (files) and .img (full disk) backups @@ -206,6 +208,33 @@ cd ~/dev/PBSClientTool sudo ./uninstaller.sh ``` +## Docker Solution (Windows/Mac) + +Want to backup Windows or macOS systems?
