Bvckup 2 network drive11/23/2023 These are added by the "network monitoring" module, which is also responsible for the drive resuscitation. Take a look in bvckup2.log for entries starting with "Netmon". It *used* to work fine, when I last checked it a couple of years ago, but Microsoft might've patched thing up since then. That said, Bvckup2 has a piece of code that attempts to resuscitate mapped drives using poorly documented Wnet function. In recent Windows versions (Vista+) there appears to be some logic that requires an interactive access to a share to "unlock" its credentials from the protected storage and establish an actual SMB connection. I believe this has to do with how Windows caches/stores share credentials. But if they are nearly the same, then it's not. If they are substantially different, then delta copying is beneficial. Generally, yes, this sounds like a good case for delta copying, but you can evaluate it yourself - run the backup, look at the last entry in "Running the backup" section of the log and compare "read" and "wrote" counters:Ĭompleted in 52 min 33 sec with no errors Would you recommend I still use delta copying or full copying in this case? This presents a problem if the device is removed or disconnected right after a program (like Bvckup 2) reports that the writing is completed, whereby in reality Windows is still busy writing stuff out to the device.Ģ. Normally, Windows would accept write requests and actually put them through to the device a bit later on - this is called "write caching". Is there any risk to turning off flushing?įlushing ensures that all data that the is _queued_ to be written is actually written out. This is the only thing holding me back from purchasing the pro edition right this moment.ġ. I have it on Delta for now but can switch to full copy if you guys advise for speed sake when doing Local -> Network.Īny help really with the flushing write cache issue would be greatly appreciated. I am not sure what is faster - delta copying or full copies as I'm still doing my initial copy. The max_io_buffers do seem to stick though. Is there anyway you can think of that could help me speed this up? I have tried opening the individual settings file for my backup (after app is closed) and altering the below 4 lines, but whenever I reopen Bvckup, it reverts the Flushing line items to "2". This is obviously very slow compared to just straight copying from Explorer to my Network drive. This can last anywhere from 10sec for 100mb files to upwards of a a few minutes for large files. With Bvckup, I notice that the file copies very fast, but then it gets stuck on Flushing Write Cache after every single file. Synctoy was having issues writing fast enough to my Network Drive. I'm trying to create a weekly backup of my external drive to a Network Mounted Google Drive (using NetDrive) for large files (videos, sometimes in excess of 10GB each). I just downloaded Bvckup 2 trial after hearing about it potentially being a replacement to my trusty Microsoft Synctoy 2.1.
