Backup Scripts

Simple Deno backup scripts for file and folder backups.

Run

• Backup: deno task backup <config-path>
• Restore: deno task restore <backup-directory>
• Test: deno task test

[[tasks]]
src = ["/path/to/source"]
dest = "target"

Backup behavior

The backup task supports these copy modes:

1. Single file to destination file

   • Example: src = ["/a/file.txt"], dest = "file.txt"
   • Result: copied directly as <backup-dir>/file.txt

2. Single file to destination folder

   • Example: src = ["/a/file.txt"], dest = "files"
   • Result: <backup-dir>/files/file.txt

3. Single folder to destination folder

   • Example: src = ["/a/folder"], dest = "folder-copy"
   • Result: folder content is copied as <backup-dir>/folder-copy/...

4. Multiple files/folders (mixed) to destination folder

   • Example: src = ["/a/file.txt", "/a/folder"], dest = "bundle"
   • Result: each source is copied under <backup-dir>/bundle/

5. Compression to 7zip

   • If destination ends with .7z, sources are compressed.
   • Example: dest = "bundle.7z"

Optional fields

• before-command (array): commands to run before backup copy/compress
• commands (array, with type = "command"): command-only task
• os (array): run task only on matching OS
• restore (bool): include or skip this task during restore
• filter-source (bool): disable source filtering if set to false

Example command-only task

[[tasks]]
type = "command"
commands = ["date > /tmp/backup-date.txt"]
