1. Scp speed limit 1m

Scp-l 1000 file name account @ remote machine IP

At this time, the transmission rate is about 1M/8=100K.

2. Rsync is (limited to 100k Bytes/s):

Rsync-auvzP--bwlimit=100 local files remote files

Parameter description:

V: detailed prompt

A: operate in archive mode, copy directories, symbolic links, equivalent to-rlptgoD.

Z: compression

U: update only to prevent new local files from being rewritten, pay attention to the clock of both machines at the same time

P: it integrates the two parameters-- partial-- progress.

So the rsync at this time supports the continuation of the breakpoint.

Transferring files between computer rooms is generally worried about taking up too much bandwidth, especially in the case of shared bandwidth. Two commonly used software can limit speed:

Scp can add the-l parameter:

-l limit

Limits the used bandwidth, specified in Kbit/s.

Rsync can add-- bwlimit parameter

Quote

-I,-itemize-changes output a change-summary for all updates

-- log-format=FORMAT output filenames using the specified format

-- password-file=FILE read password from FILE

-- list-only list the files instead of copying them

-- bwlimit=KBPS limit Imax O bandwidth; KBytes per second

-- write-batch=FILE write a batched update to FILE

-- like-- write-batch but Whampoo updating dest

KBs is the abbreviation of KByte/s, and Kbit/s should be Kbps (abbreviated to KB/s). KB/s is usually used for transfer speed, such as when copying files. Kb/s is commonly used

At broadband speed, such as 512Kb/s.

Broadband is usually installed in kilobytes per second, but the actual download speed is completely different from the usual kilobytes. For example: 512kbps broadband, download speed per second

512 / 8=64KB/s .
