![]() The value that you add is measured in MB. If you add values that are out of range, your computer will revert to the default behavior. Maximum value: Total physical RAM in MB divided by 2 Minimum value: Total physical RAM in MB divided by 64 supposed to set file system cache when copying from fast drive to slow drive, but I experienced the large caching even when copying from fast drive to fast drive): ![]() I eventually found a registry key that allows you to control it (only tested on XP Pro 圆4 SP2):Ĭreate new registry DWORD value SystemCacheDirtyPageThreshold at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\MemoryManagement and set to 0x40 (64MB) (ie. re-badged Windows Server 2003) and found that it used excessive amounts of RAM when caching large file copies (appears to be a feature of the Server OS). ![]() a Windows issue rather than liquesce), and for informational purposes.

So, My question is, Is it normal for the flushing operation to take awhile?Īlso, is there an option to have the filename truncation in the GUI as it's copying to not get cut off as much? This means that when the file is done copying, theres quite a writing 'debt' accumulated in the write cache and thats why flushing this cache takes this long. That and I think it's a good 'weird' scenario to put a beta backup program through. When full that array will be 5tb, so I've been working on a solution that allows for easy backup and a pool of large USB disks fits the bill (aka budget). Basically it's a software JBOD Volume, and I've just started using it to pool 2 3tb usb externals to backup a big array. There haven't been any errors sofar, but it's obviously going to take awhile to complete.īackground: This particular backup is different from my others in the respect that it's being done from a network share to drive pool powered by liquesce ( ). Nov 27, 2013I've started a new backup of ~3tb of data (>500,000 Files) and I've noticed on some of the bigger files are sitting on "flushing" in the gui for awhile.
