I run a nightly backup, which takes about 1 hour. During that the performance is bad as hell.
It looks pretty much like this:
# DB dump ionice -c 3 nice -n 20 mysqldump --skip-lock-tables --user=foo --password=bar DBname > dump.sql ionice -c 3 nice -n 20 gzip -9 ... dump.sql.gz # copy to new backup folder ionice -c 3 nice -n 20 rsync -a /backup/path/files # delete old backup folder ionice -c 3 nice -n 20 rm my/old_backup/path/ -rf
I think the rsync is killing it.
Do you see any improvement?
