If you have the whole vps kloxo backup file then :
To restore:
/script/restore --restore --accounts=all <backup-file-path>
To list the contents of a backup file.
/script/restore --list <backup-file-path>
To restore only certain domains/clients
cd /usr/local/lxlabs/kloxo/httpdocs/
lphp.exe ../bin/common/restore.php --restore --accounts=domain:domain.com,client:clientname <backup-file-path>
If you have taken the backup under a specific client, and want to restore under the same client, you can provide the client's class and name via --class and --name respectively. You have to first make sure that this client exists in the system. That is, you have to first add a client with the clientname, and then you can restore the backup under him.
cd /usr/local/lxlabs/kloxo/httpdocs/
lphp.exe ../bin/common/restore.php --class=client --name=clientname --restore <backup-file-path>
May this help you ..
