Now after saving for the fifth time, I realize that I had accidentally deleted some vital info. How can I retrieve that? I just open eg. .recycled/my_doc$AAB, copy the info that was not deleted at that time and paste it in my current doc. Now here's my question: Is there a file system for GNU/Linux with a
similar
feature? I would at least like to have my ~ partition to use such a file system.
Sounds like an ordinary backup or RAID to me. It's definitely no ordinary backup or RAID. It even works with a single hd. SFS takes care of all this. I don't have to backup anything. SFS just writes all subsequent copies of a file to different locations on the hd and moves the existing ones to .recycled (well, in fact it only updates the TOC). .recycled is just a hidden directory where all previous copies of a file are stored. This also means that in the rare case of a system crash when saving a file, I only lose that part of my work that was in memory only. The copy on disk remains untouched because only AFTER a new copy is written to disk (to a different location), the old copy will be moved to .recycled and the TOC will be updated. But in case of a crash during save, the new copy isn't finished and thus the old copy remains untouched and no TOC update is necessary. This whole process is completely hidden for the user. .recycled only comes to mind when I have to recover some data. Manon.
