  • I've kept the gzip compression at a low level, but depending on the cpu power available on the source machine you may want to increase it. However, SQL compresses really well, and I found even with -1 I was able to transfer 40 MiB/s over a 100 mbps wire, which was good enough for me.

    ssh 10.0.0.4 "cat /tmp/backup.sql | gzip -c1" | gunzip -c > backup.sql

  • If you have servers on Wide Area Network (WAN), you may experience very long transfer rates due to limited bandwidth and latency. To speed up you transfers you need to compress the data so you will have less to transfer. So the solution is to use a compression tools like gzip or bzip or compress before and after the data transfer. Using ssh "-C" option is not compatible with every ssh version (ssh2 for instance).

The compress option is pretty standard. I have it available on Ubuntu 12.04, Linux Mint 13, FreeBSD 9.2 and 9.3
