Background: 🈶 ⛪ → 🌿
→ 📧 In the recent decade, organizations are replacing courrier with email. The reason is two-folded. 🌿 First, the later is more environmentally-friendly. 📨 Second, the later delivers the content to the recipient quick as a flash.
📧 📎 When one sends an email, one sometimes wants to attach a file to an email. If one has to sign a paper document and send it by email, then one will probably need a scanner. (Despite the emergence of scanning apps on mobile devices, the quality of a scanner is normally better since the page is flattened during the scan.)
Problem 📄 💾 → 🖥 / ☁
The documents are often saved to some local/cloud storages. How to manage their versions?
Solution Primer
Add a date to file name.
However, when one has hundreds of unorganized files in a folder, how can one
deal with foo-bar-2018.odt and 2018-foo-bar.odt?
Use rsync
rsync is a quick solution, but it doesn’t scale. One has to do the backup
for each machine. That’s no big deal for several devices, but that’s not
the way for sharing files among an array of computers.
Use git-annex
git-annex is like a librarian. Only symbolic links 🔗 are written into the index. The binary files are stored as
binary objects under 📁 .git/annex.
