We are 5 who have a dedicated server with MCHost. At the moment we do a daily backup which runs between 4:30 and about 7:00 GMT. (We are some Americans and some Europeans.)
But one of us als has customers in Austrialia/Asia. The problem is that during the time the backup runs the load goes above 1, 2, sometimes even 5, 6 or 7 and the server seems to feel slow during that time. The CPU is though idle most of the time (60 to 90%), but the disk has quite something to do. I'm no expert, but I assume the limitting factor is the disk here.
Is there anything that we can make backups but the server is not so slow during that time? Is it usuall that a complete backup lasts so long? (We have about 200 accounts, most of them really small but some big ones. The home partition is 6.73 GB.)
Does the backup in WHM run with low priority? Can we configure it that it runs with low priority? Does this help?
Or is it possible to exclude some files from the (daily) backup (like 10MB Videos, ...)
Then there is now an option in WHM to use incremental backup. Does anybody know anything about that. Is there a full weekly backup and a daily incremental? How is this backup restored? Like the full daily or do we have to restore the full first and then the incremental?
Thanks!
