In the window that opens up, search for this line (roughly 10 lines down): .
Double-click on the results of the search. This is most useful with a lot of smallish files. Then click on the magnifying glass icon near the top of the folder window and paste this into the search window that popped up: GlobalSettings.XML. If you have large files this won't matter as much as each file will have time to saturate the network bandwidth on it's own. It would also be possible to make a ssh tunnel and use netcat over that encrypted tunnel.Äepending on the size of the individual files this can save as much as 40% or more in copy time. This works very well and is a great way to boot a laptop with a USB Linux system and extract the data to a remote host. The result is it will speed it up and you don't need extra elbow room on the source host as the compression never hits the disk but is redirected via the pipe to the raw network port. This causes the copy process to create a huge single file redirected to the network port and that will saturate the network quite nicely. ![]() There is a technique to on the fly compress the files and directories and pipe them through a raw network port where a receiving host is listening and then decompress on the destination. Each file one after the other is copied and the bandwidth is barely a blip. If you are needing to copy a large number of small files from one host to another over a network, you will find that it takes a very long time. Maybe you could find a host close by the SAN to act as an additional host. (Please note, I am using a modified version of gnutils cp.) Read here for more info: įor srcdir in `date +"%r"` $srcdir start > PrUv2CopyTimes.logÄ®cho `date +"%r"` $srcdir finish > PrUv2CopyTimes.logĬat PrUv2CopyTimes.log | mailx -r LouPrBoxen001 -s "Backup Complete" so sure if this will work for the original question as the SAN isn't exactly a host, just a networked storage array. but I can't find any native methods available to Linux.Ĭould something like Python or Perl be of assistance? Is there something I'm missing? What are your thoughts? There are MANY ways to do this in windows. :) I need a way to spawn multiple threads in a file copy. sources areÄue to the nature of our SAN, single threaded file copy is not very fast but it is very capable of 600+mb/sec if we ask it in the right way. It is 15 disks presented from a SAN over Fibre Channel and being copied to a local array consisting of 22 spindles. I have a "large" amount of data that needs to be copied every day.
