Zotero is an open source plugin for Firefox for managing research papers collections. You can use online zotero storage (pretty small) or use third-party sync application. I use Yandex Disk for this purpose: 10 Gb it quite enough for a moderate research library. zotero can automatically fetch article metadata (author, year, etc) from the web (like Mendeley and similar software do).
We all do backups. This note is about doing them on Ubuntu 12.04.
- archive important folders
- dump mysql databases
- upload all to yandex.disk (online web storage with 10GB space)
- delete old backups
I’ll save only backups for last five days.
