Limit rate of backup
Full weekly backup for all domains create a huge I/O throughput on our SAN that stress too much our infrastructure until backup ends. It would great if we can tune data through a pipe like "pv" command do.
I.e.
This is an example of backup that stress the SAN:
mysqldump -A -q --single-transaction=TRUE -u $MUSER -p$MPASS | gzip > $_file
This instead is and example that do not stress the SAN:
mysqldump -A -q --single-transaction=TRUE -u $MUSER -p$MPASS | gzip | pv -L 512k > $_file
in the last command we set the maximum rate limit of 512k. Of course backup will take longer but with less impact on storage infrastructure.
