saver

Saver is a self-contained cross-platform save-scumming/backup utility.

Now at version 0.9.4 I'll be updating the examples here only on user-significant changes.

Features:

• Handle single file and directory saves
• Directories are backed up as zip files
• Option to annotate saves
• No dependencies, single binary
• Tested on Linux and Windows (i386/amd64)
• Keeps track of space usage (and you will use space)
• Has a spinner thingy so you can see it ain't dead
• Minor bugfixes and improvements since the version from 2014
• Can also do MD5 checksums of backups
• Starting to add shorter/scriptable output modes

Binaries

Binaries are back! This time for more platform-arch combinations thanks to the awesomeness of Go 1.5. The binaries are distributed outside of the repo, but md5 checksums are kept here for some notion of "authenticity".

Building on your platform is as simple as go build, and cross-compiling is as simple as make (assuming you have Go 1.5 or newer).

And now the binaries link is public. Apply caution please!

Usage notes

Copy the binary wherever you want and run it from command line (for Windows folks that's via cmd.exe). By default the directory where the binary resides will also be the directory where the config/db file is saved and where the game directories will be made.

Note that restoring a save won't stash the current save, i.e. it will overwrite it without any prompts.

Games

Some great games where saver may be useful:

• NetHack
• Dungeon Crawl Stone Soup
• Cataclysm: Dark Days Ahead
• Dwarf Fortress

saver's Issues

Add monitoring mode

Apparently much more complex to implement, but also much more useful is to have an ability for the program to monitor the saves folder and backup when changes (and/or on time interval).
