![]() Read up on master & slave connections in the ssh manpage. The slaves will piggyback on the master connection which stays open throughout and won't ask you for a password. Open an SSH master connection to the remote host and run several scp commands as slaves of that master.For this example, the private key is at /.ssh/my-ssh-key. Use a different command than scp, like sftp or rsync, or Use the scp tool to copy a file from your workstation to the home directory of the target VM.There are two options I am looking at: 1). I will show you how to establish a SSH connection to another server in this post. Usually I need to transfer around total of 800 gb files that is made from around 16000. I think that the most useful tools for this is Midnight Commander (mc). If you cannot express all the files you want to copy as a single glob pattern and you still want the copy to be done using a single command (and a single SSH connection which will ask for your passsword only once) then you can either: Tag Archives: copy files fast ssh How to Copy Files Between Servers via SSH Using Midnight Commander If you are a system administrator, you should often need to copy files between servers. The single quotes are to protect the glob pattern from being interpreted from the shell on the local system. Ĭopies all of the files from the remote system which are names (something).tar.gz and which are located in subdirectories of /tmp whose names begin with a, b, or c. Update: As requested, here you go with a pure PHP solution - had some. Here is an example for the linux command line: userlocal cd /source/ tar czf - ssh userremote 'cd /target/ tar xzf -'. ![]() Magnitudes faster than pure scp, particularly with regard to many small files. For example: scp 'RemoteHost:/tmp/*/*.tar.gz'. Using gzipped TAR through an SSH tunnel is blazing fast. This usage will only support a single destination folder on the local system for all files though. P port Specifies the port to connect to on the remote host. The most common options: -p Preserves modification times, access times, and modes from the original file. These are less resource intensive than the built-in copy function in Windows.If you can express all the names of the files you want to copy from the remote system using a single glob pattern, then you can do this in a single scp command. The scp command syntax has the following syntax structure: scp OPTIONS usersrchost:file userdesthost:file. It’s also a good idea to pause your antivirus, as these are known to eat up resources at times, especially during scans.Īlso, if the freezing occurs often, consider using a copying tool instead. The best way to help reduce freezing issues is to close all other open apps. Im afraid, however, the copy wont be much faster than 85 MB/s. Since the copying process is so slow, you may have other programs running at the same time. Typically, this is because copying is a resource-intensive process. Sometimes Windows freezes up during the copying process when you try to copy a large number of files in Windows. ![]() Dealing with Windows Freezing During Copying While the built-in compression tool in Windows works well enough for text files, it doesn’t always offer optimal compression for images and videos. It takes a few minutes to compress your files, leaving you with one large file which copies very quickly. This can work when moving many small files by archiving them with WinRAR or 7zip for better compression ratio. FF Copy (free, but isn’t updated often).Fast Copy (ideal for creating backups and free).If TeraCopy doesn’t work well enough, you can also try:
