As such, I use Plesk to initiate the backups because Plesk adds all sorts of extra magic to the backup that makes consuming it during a restoration procedure very safe. I can hear you ask: "So wait, why do you even need to make a backup file? Why not just rsync the source files and folders?" Because an annoying thing called "Plesk" is in the mix! This is my client-facing web host which uses Plesk for convenience. To view the top process (by utilization), you can execute nmon and press t If. rsync isn't actually doing the transfer nor can it because I can't even spare the space to save the backup file. This NetHogs bandwidth monitoring solution is available across numerous Linux operating systems. It is possible to monitor CPU and memory usage on Linux with a Bash script. Why is that important? Because that would seem to invalidate the use of the venerable rsync -bwlimit. Enter SSHFS! The backup is saved to what is ostensibly a local drive so that no backup bits are ever on the web server itself. NetHogs does not rely on a special kernel module to be loaded. Stepping back, I had a problem with not having enough local space to create the backup itself. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. I could increase my available throughput, but that would merely mean that the network transfer would complete faster, but still max the total capacity of the connection while doing it.) (Unfortunately, I can't add an interface to dedicate to backups. Unlike the other commands on this list, ps presents the output as a static list, not updated in real time. The ps Linux command creates a snapshot of currently running processes. This could be on the server or client side that is, I'd be happy to do this on either the client that initiates the connection or the server that receives the connection. List Running Processes in Linux by Using the ps Command. Is it possible to limit a process's maximum allowed throughput to a network interface? I would like to limit the SSH-based file transfer to only half of my available bandwidth. I am concerned that visitors to the various sites that the server hosts will experience degraded performance while the backup is transferring across the network. I have a CentOS 5.7 server that will be backing up its files nightly.
