Large backup and low system resources

[jasne]

Hi,

I have to backup 4 users:

user_1 (total 11GB tar.gz) - mostly imap files, over 10k
user_2 (total 35GB tar.gz) - various data: mysql 1GB, imap files 27GB (over 20k files) , other data (html php) 8GB
user_3 (total 2GB tar.gz) - mostly imap files, over 3K
user_4 (total 2GB tar.gz) - mostly imap files, over 3k

So, earlier system did backups and send to remote host at 4-5 a.m. where was lot of free server resources. Everything worked fine.
But now files growth and sometimes system send me an email "Warning: The system load average is 127.31"... and then system freeze...

So Im looking for a best solution to make backup above users everyday and send to remote host, doing so does not make system freeze

Please check http://help.directadmin.com/item.php?id=335. You may also want to check for incremental backup solution (there are many 3rd party products for that like BackupPC or just a simple rdiff-backup).

so I found that DA support some features (http://www.directadmin.com/features.php?id=577)
I've checked directadmin.conf but haven't found "backup_nice=19" , is this mean that is backup_nice is set default 19 ?
