Depends on the configuration: static or dynamic pages.
It also depends on how much data you can afford to loose and how fast you want to be back up and running.
A simple mechanisme:
If static just an rsync to an external provider. If dynamic you will hae to backup the database as well.
I use Amazon s3, and manually ftp backup. The only shortcoming is not fully automatic, normally, it takes me 1 hour to backup about 6 gigs of data. I do weekly backups. If you're looking for daily backups, then, I'd recommend using a service like r1soft. Would also recommend keeping a backup on your local hard drive, and a backup on a remote server.
1-what is differnce between hiring cheap server and sending file
by ftp and r1soft software? ftp sending is not automatically?
2-what is the necessity of having remote back up ? local back up
is not enouph? have you seen the disasters...
For your first question, if you would transfer your files every day to another server by FTP, it would generate a lot of traffic and a lot of load on your server.
Also, if there is a failure that is difficult to recover from (e.g, OS corruption that requires you to reinstall), you will not be able to easily - and quickly - restore your server to it's original state.
R1Soft backups your entire disk (including your OS and it's configuration) and allows you to do a bare-metal restore which essentially allows you to restore everything from A to Z.
R1Soft also backups your entire disk once and then only backups the data that has changed since the last backup occurred, thus avoiding a lot of bandwidth and resource usage that can be used elsewhere.

For your second question, remote backups allows you to protect your data in case of disk failure and of course, against disasters also.
if one day the disasters happened the second hard that receives
data`s by R1Soft backups is on the same data center or out of the data center?. i mean if one day as example data center fired(like what happened for theplanet.com before..) the data`s that has been saved on remote server will be destroyed too.sorry for my poor english
I mean back up is out of data center by using R1Soft backups ?
Well, let's put it like this:
- With backups done on your own disk, if there is a disk failure (which is unlikely by itself), you will lose your data.
- With backups done on a remote server, in the same datacenter, the scenario above would allow you to recover your data
- If there is a major disaster at the datacenter (which is very unlikely), then there are off-site backups.
Offsite backups are usually provided by default, however, I am not personally familiar with our infrastructure on that level.
Also, if you'd really like to do backups on your own disks, we recommend to have at least a RAID-1 array (software or hardware) so that if you lose one disk, you data remains safe.
Plesk has a backup option with remote FTP, lookup for a VPS server, or a backup provider.
you only need a private secure server with FTPD installed on it, plesk panel will do the rest for you.
it seems it is good idea for me too
does plesk automatically sends files to another server perfectly?
do you have any experiece with this way? I choosed vpsland
as second server.it needs less money than r1soft and also it is
out of my data center. my data is only less than 1.5 gigs.
the software is great...I agree but if i want to use it
i have to pay 50 dollars for 50 gigs space(my data center told)
but it seems i can get one acount of vps servers (10 gigs space
24 dollars) and pay less money...or even (6 gigs space 10 dollars)
I make plesk to send daily or weekly...oautomatically or handy.. http://www.vpsland.com/windowsplans.html
my main data is just 1.5 gigs.
