Fornit Posted September 14, 2009 Report Share Posted September 14, 2009 2 Config files"%profile%\Application Data\uTorrent\resume.dat" "%profile%\Application Data\uTorrent\settings.dat" are getting killed with every OS crash. uTorrent is overwriting them every minute, and if my computer crashes or freezes, those files are gone.I have to use special bat file to save them every day, otherwise I risk to lost them permanently. uTorrent need "safe write" feature, like in eMule. This soft have to be crash-proof. Link to comment Share on other sites More sharing options...
DreadWingKnight Posted September 14, 2009 Report Share Posted September 14, 2009 Solve the cause of your OS crash and you won't need this. Link to comment Share on other sites More sharing options...
Firon Posted September 14, 2009 Report Share Posted September 14, 2009 It does do an atomic write. It writes a .new file, moves the .dat to .old, then moves .new to .dat.But fix your PC crashes, seriously. Link to comment Share on other sites More sharing options...
Fornit Posted September 16, 2009 Author Report Share Posted September 16, 2009 Firon, I'm working on my faulty hardware, I already bought a new computer parts. But that's not the point. Software must NEVER, under ANY CIRCUMSTANCES, destroy it's important data. eMule, for example, satisfy this condition. And uTorrent has many cases of killing it's config already, atomic write is not working? Link to comment Share on other sites More sharing options...
moogly Posted September 16, 2009 Report Share Posted September 16, 2009 Come on, I have already seen other programs killing its own files, e.g. Firefox after a crash got the user profile corrupt. Link to comment Share on other sites More sharing options...

Firon Posted September 16, 2009 Report Share Posted September 16, 2009 Atomic writes can be screwed over by caching. A crash while data is still cached (in RAM or in your HDD's cache) can result in a broken state if timed just right, regardless of the write being atomic. It's not a cure-all.

Fornit Posted September 17, 2009 Author Report Share Posted September 17, 2009 1) Agent Forte files was NEVER corrupted by system crash (I using it since 98).2) Same about eMule and Miranda.3) I know about FF. My bat file backuping it as well. But they creating a solution - sqlite bases, for example.What uTorrent needs to do, is chain backup writing. Old resume.dat renamed to resume.01.old, resume.01.old renamed to resume.02.old, and so on - up to 10.old. If resume.dat is zeroed, UT looks in resume.01.old, if it's zeroed - in resume.02.old... You got the idea.Before I set up the backups, I had to run NT Undelete to recover erased copy of resume.dat. And it worked. So you simply don't need to delete resume.dat too soon.

richms Posted June 10, 2010 Report Share Posted June 10, 2010 Could it keep a few of the old ones around. I have just lost an 8 meg resume.dat file when I plugged in a USB device that did something stupid, thats about 500 torrents I will have to readd, retarget to the files on the NAS and let check since my last backup of the user directory that has a resume.dat in it.Crashes happen, the app should be able to roll back to previous ones, ideally without me doing anything when relaunching it.
