really long backups

[gbh1935]

When I do my weekly backup the process will peg my box for almost 12 hours. The backup that appears to take the longest is the backup of a multiforum site that has about 20,000 tables in a mysql database. Do you have any tips on shortening the backup time?

Its simple, just skip that account from Main >> Backup >> Configure Backup >> Select Specific Users.

Just uncheck that user.

Clean up large accounts.

Wht does the weekly backup take any more time than the daily? Same procedure.

I believe it would depend on the type of backup. If it's incremental backup, i think weekly backup run would take longer ... just a guess. I have incremental backup set and weekly backup's do take a bit longer than daily one's.

AFAIK, the backups are the same. I know all the file dates and sizes are the same. I believe it just copies the files over to weekly when it it done, and that is why it takes longer.

Yup, the backup does the most frequent one first (usually daily) and then simply uses rsync to copy daily/ to weekly/,etc - might take longer due to I/O contention.

I do a incremental backup which then means it does not tarball and gzip and uses rysnc instead. Much less load and a lot faster. I also use a different rotation scheme - I use either rdiff-backup or rvm. That way I can keep backups for over a month in the same or less space than daily weekly monthly.

Obviously more disk space, but disks are much cheaper than time.

If I change to incrimental from full, will it automatically remove the old gz backups and start fresh?

It will leave them alone. You'd have to delete them if you don't want them any more.

WHM/cPanel has no way of knowing that you don't want to keep the old backups.

Just put in the cron to delete them before it makes the backup.
