Incremental, cross-platform and multithreaded backup tool written in Rust
Documentation
# rbackup

**rbackup** is a fast, cross-platform, and multithreaded command-line utility written in Rust for performing incremental backups of directories. It is inspired by tools like `rsync` and `robocopy`, but designed with simplicity, portability, and localization in mind.

## ๐Ÿ”Ž Exclude patterns (`--exclude`)

`rbackup copy` supports flexible exclude patterns to skip files and directories during a backup. The `--exclude <PATTERN>` option can be used multiple times to provide multiple glob patterns.

Where patterns are matched

- By default patterns are matched against the path *relative* to the source directory. Example: with source `/home/me/project`, pattern `build/**` matches `/home/me/project/build/foo`.
- Use `--absolute-exclude` to match the pattern against the absolute path of the source file instead.
- The matcher also tests the file basename (the filename only). This means a simple pattern like `$RECYCLE.BIN` or `Thumbs.db` will match files whose name equals that string anywhere in the source tree.

Case sensitivity

- By default matching is case-sensitive.
- Use `--ignore-case` to enable case-insensitive matching for exclude patterns.

Examples

- Exclude macOS DMG files and Thumbs.db files (case-insensitive):

```bash
rbackup copy /source /dest --log backup.log --exclude '*.dmg' --exclude 'Thumbs.db' --ignore-case
```

- Exclude the Windows Recycle Bin directory by basename and hidden files starting with a dot:

```bash
rbackup copy /source /dest --exclude '$RECYCLE.BIN' --exclude '.*'
```

> Tip: In `zsh`/`bash` wrap patterns that contain `$` or other special characters in single quotes: `'\$RECYCLE.BIN'` or better `'$RECYCLE.BIN'`.

Absolute vs relative matching

- Relative match (default): `--exclude 'temp/**'` will skip anything under `source/temp/`.
- Absolute match: `--absolute-exclude` with `--exclude '/home/me/project/temp/**'` will match only that absolute path.

Dry-run and logging

- Combine `--dry-run` with `--log` to generate a report of what would be copied or skipped โ€” but without changing the destination:

```bash
rbackup copy /source /dest --exclude '*.tmp' --dry-run --log dryrun.log
```

- The log file contains both `Copied` and `Skipped` entries. Skipped entries include the exclude pattern that caused the skip when applicable, which helps debugging complex exclude sets.

Use-cases

- Backup only source code files, ignoring build artifacts:

```bash
rbackup copy /home/dev/project /backup/project --exclude 'target/**' --exclude '*.o' --exclude '*.class'
```

- Mirror a user's Documents folder but exclude large media files and the Recycle Bin:

```bash
rbackup copy ~/Documents /mnt/backup/Documents --exclude '*.mp4' --exclude '$RECYCLE.BIN' --exclude 'Thumbs.db' --ignore-case
```

- Debug why a file is skipped: run a dry-run with logging and inspect the log โ€” each skipped line shows the pattern that caused the skip.

## ๐Ÿ“ Example

```sh
rbackup /home/alex/Projects /mnt/usb-backup --log backup.log --timestamp
```

## ๐Ÿงช Build from source

To compile rbackup yourself:

```sh
git clone https://github.com/your-username/rbackup.git
cd rbackup
cargo build --release
```

For Windows, rbackup.rc will be embedded automatically in the executable.
