autozippy

Description

AutoZippy is an easy to use automatic (non-interactive) archival software, designed to help you automate backups. Archive creation is configured with a simple and intuitive .YAML preset.

For creating archives built-in library tarfile and 3rd-party library py7zr are used.

Limitations

Currently AutoZippy supports only 7z and tar archives as 2 most popular formats. Tar archives currently do not support encryption due to a lack of non-interactive GnuPG assymetric encryption in python. However, nothing prevents you from encrypting a tar archive inside a 7z one.

YAML Preset

YAML presets consist of archives and their settings. Every setting can be specified either on a file-wide level or overriden for specific archive with the notable exclusion of timestamps - they currently can only be specified on a preset-wide level. Aside from universal settings, like output directory, every format has its own specific settings, like algorithms, header encryption and compression level.

Archives and their settings are specified under archives. There they are listed by their filenames and each has to contain at least one file under its own files section. If you want to backup all files from directory but not subdirectories you can specify '*' as a filename.

Usage Examples

autozippy cloud.yaml photos.yaml example.yaml

As many configs as you want can be provided. -v/--verbose can be provided for debugging information and time per preset.

Example config is provided under filename example.yaml

Settings

• mode - must be specified - archive format, can be either 7z or tar
• outdir - directory where archives are going to be saved. Default is working directory.
• root - directory from which to start path inside of an archive. For example, /etc/nginx/sites-available/yoursite with the root specified as /etc/nginx is going to be saved as sites-available/yoursite in the archive. Default is start of file paths you specify in config.
• pass - password

File-wide Settings

• timestamp - (true/false) whether to add timestamp to a filename of the archive. False by default.
• custom_timestamp - specify custom format for a timestamp. Default: %Y-%md-%d. See details here

7z Specific Settings

• algo - compression algorithm. Can be either lzma2, lzma, bzip2, ppmd, deflate or store if no compression needed. LZMA2 by default.
• lvl - supported only with LZMA2 - compression effort level
• crypt_h - can only be used if pass is specified - whether to encrypt file headers (names of files inside of the archive)
• native - whether to use 7z program installed on your computer instead of python library. The only way to enable multi-threading. Requires 7z in your PATH.

TAR Specific Settings

• algo - compression algorithm. Can be either xz (lzma), gz (gunzip) or bz2 (bzip2). No compression by default.
• lvl - supported only with LZMA - compression effort level
