I’m a bit late covering this one but a few weeks back it came out that Yahoo are getting rid of delicious. Despite their claims they will find someone to take it over, I really don’t trust the fact that one day it might just get turned off. So I decided to write a simple cron that uses their API to backup my bookmarks every three hours and run it on one of my VPSs.
0 7-23/3 * * * curl https://username:[email protected]/v1/posts/all > /home/user/bookmarksBackup/$(date '+%Y%m%d-%H:%M').xml
Just add that entry to your crontab changing the username, password and path where you want to save it to appropriately. That’s it simple backup just in case Yahoo make an even worse decision than they already have.
