cpbackup will back up all of your accounts' data either daily, weekly or monthly. The documentation for cpbackup is available here:
Backup
To make a one-type backup of a single account, you can use /scripts/pkgacct. Its syntax is the following:
Code:
# /scripts/pkgacct $cpanelaccountname
where $cpanelaccountname is replaced with the actual name of a cPanel account to be backed up. /scripts/pkgacct will create a tarball (.tar.gz file) that can be copied to any location you choose, even to a different server.
/scripts/pkgacct creates the same type of backup file that the backup system in the WebHost Manager creates.
