diskbackup

diskbackup is a very simple backup tool. Main features:

• The directory dest will be a clone of src (and its subdirectories). New files or modified files will be copied, and files in dest which are not in src will be removed.

• The backup is incremental: only new or modified files will be copied. filename + file size + modification time are used to do the comparison between source and destination files.

• Supports exclude patterns (case insensitive)

• Follows symbolic links

• Works when the dest is a network shared folder (tested on Windows)

• The source code is ~50 lines of code: you don't even need to scroll in your text editor to read the code, it takes only one page ;)

Installation and usage

You need Python 3.6+, and to do:

pip install diskbackup

(An alternative installation method is to just copy the single file diskbackup.py where you want to use it.)

This is how to use it:

from diskbackup import backup
backup(src=r'd:\docs', dest=r'i:\docs')                  
backup(src=r'd:\docs', dest=r'i:\docs', fake=True)   # fake run, no change on destination
backup(src=r'd:\docs', dest=r'i:\docs', exclude=['excluded_dir', '.mp4'])   # the src file list will ignore these patterns
backup(src=r'd:\docs', dest=r'i:\docs', exclude=['excluded_dir', '.mp4'], excludefromdest=True)  # the src and dest file lists will ignore these patterns
