Hello. I had a system crash yesterday, a raid failure (one hdd died from a raid 0), I reinstalled Windows 7 x64, on a new hdd (normal, not in raid or something like that). I installed them Firefox 18 and I set up the Sync account. Then I tried to synchronise my computer with the server, after 10 minutes or something, when I came back to the computer, I checked the bookmarks. And surprise... some sections were lost, after a 2nd synchronise, all my bookmarks were lost and nowhere to be found. Also on the server there are no bookmarks left, even if the passwords still work and all in pristine condition. So what to do now?
Sorry for your loss of data. Sync wasn't intended a a backup medium (it is intended to synchronize Firefox data between multiple device or Profiles) and the Sync server doesn't keep backups of user data (the "original" data should still be on at least one device connected to that Sync account in the case of failure or loss of one particular device).
Have you disconnected from the Sync server and attempted to restore a backup from within the new Firefox installation? That might get back what you lost as a result of running the 2nd "sync" at least. From my own observations while using Sync, Firefox usually creates or updates the backup file quickly after a "sync process". It does only retains one "backup" for each "day", but it doesn't wait to make the daily backup at a specific time - it seems to be an ongoing process.
Beyond that, unless you have another "backup" of your data, you're SOL with your data.
Hello for the answers and the ideas but as I've figured it myself, I do also understand that this is not a service that can ce recovered after one might uninstall or forget to sync the data between more than one computer. I've read about it and well yes the service doesn't work as a normal back-up system but rather as a system that depends on other syncs with other computers/devices. Thus it's not a system that should be used by a person with just one computer, sync can be replaced by using a normal back-up/sync addon, and there's a few of those to solve this problem.
Even if I lost some bookmarks well I am quite happy that all my passwords have been saved which is 1/2 win-win for me.
Thanks for your help, at least I've understood how to prepare better for the future
