![]() ![]() Trickle -s -d 3000 -u 3000 rsync /path/to/source/ /dest/ bwlimit=1000 /path/to/source /path/to/dest/ So you can take control of I/O bandwidth using ionice utility on Linux as follows: Use ionice command to set or get the I/O scheduling class and priority for a program such as rsync or your own backup script. ![]() Some “burstiness” may be seen where rsync writes out a block of data and then sleeps to bring the average rate into compliance. Rsync writes data over the socket in blocks, and this option both limits the size of the blocks that rsync writes, and tries to keep the average transfer rate at the requested limit. ![]() For backward-compatibility reasons, the rate limit will be rounded to the nearest KiB unit, so no rate smaller than 1024 bytes per second is possible. If no suffix is specified, the value will be assumed to be in units of 1024 bytes. The RATE value can be suffixed with a string to indicate a size multiplier, and may be a fractional value (e.g. The -bwlimit=KBPS option allows you to specify the maximum transfer rate. $ rsync -bwlimit=5000 -delete -P -az -H -numeric-ids. $ rsync -bwlimit=1000 /var/www/html/ this example, pull files from FreeNAS server with 5000KB/s in current directory: $ rsync -bwlimit=1000 /path/to/source /path/to/dest/ You set I/O limit in 1000 KBytes per second: Rsync -bwlimit=KBPS -a -P /path/to/dir/ Examples Rsync -bwlimit=KBPS src -bwlimit=KBPS /path/to/dir How to keep rsync command from using all of my bandwidth Set rsync bandwidth limit to 5000 KBytes per second: rsync -bwlimit=5000 source dest.You can specify the maximum transfer rate for the data sent over the socket or network by typing the -bwlimit=RATE option to the rsync command.Open the Linux, Unix, or macOS terminal.Set rsync speed limit on Linux and Unix-like systems ![]()
