SOLVED: Local & Remote Backups

[davetanguay]

After months of testing a local and remote backup solution we have finally found one that works and doesn't overload our servers.

We cannot do full cPanel backups on the server since it causes a high load on large sites (over 4gig) and causes the servers to crash for hours on end.

So we do local incremental backups (running as nice -n19) to a secondary drive using the standard cpbackup feature within WHM.

Then weekly we transfer the /backup/cpbackup/daily backup to a remote FTP server using the script below. The backup script compresses each user's backup folder to a tar.gz file before transfer. We run the script as nice -19 as follows:

nice -n19 /root/cpbackup-ncftp.sh

You must have ncftp installed to your server in order for this to work.

It's a cost effective solution since our remote FTP server is just a Windows XP machine running Filezilla. It has an external disk array of 4 SATA II drives which is very easy and inexpensive to upgrade. We're able to backup 6 cPanel servers remotely in just over a day. Total remote backup is over 600gig.

Hope this helps someone out there! I know I can sleep at night now

You can easily do that using rSync in a single line code, also which you can put in a file /scripts/postcpbackup and this will run every time after cpbackup.
