It is ALWAYS YOUR responsibility to make sure you backup YOUR OWN website.

So it is a garages responsibility to make sure your vehicle has always got fuel in it.

You as a client has to take responsibility for your own website

You're comparing apples and oranges here.
If the garage advertises
then YES, it is their responsibility to live up to their advertisement.

As the host, if you advertise that you make backups, it is your responsibility to live up to those expectations within a reasonable limit. Keeping 3 backups (daily/weekly/monthly) is NOT a 'reasonable limit'.

Yes, it is the client's responsibility to backup their own site, no questions asked, but if you, as a host claim that you make backups, then you must make every effort to make reasonable backups available... Like I said, daily/weekly/monthly is not 'reasonable', it's the lazy man's way of doing things.

Just because the industry has grown lazy doesn't mean it's acceptable.

If you look at a majority of hosts they will say they take daily backups and as long as you take them you are doing nothing wrong, but it does not mean these backups are being made available to clients. infact a lot of hosts will charge a client if they want access to any backups. If like me and use cpremote and client have access to the backups you take and advertise as taking then nothing wrong is being done.
The more backups stored means the larger backup server has to be which in turn costs you more outlay, so in turn you have to charge more to clients.

We take R1Soft snapshots every 30 minutes.

We do this because it's convenient for us.

We could charge customers for restoring their data, but we don't as the plugin makes it easy for them to restore it themselves.
This then makes it more than acceptable for us to charge to restore the data, as they are able to do it themselves.

The only caveat here is if our system can't restore it, then you should have your own backup! As we will not guarantee that we are able to restore it, just that a backup is taken.

cpremote also has a plugin that allows clients to restore backups from within cpanel, so they can do it themselves.

We would only charge a client if they want us to carry out a restore, this is only because the feature is available for them to do this themselves, so no need for us to do this

I used CPRemote in the past and just did manual backups for a while and then used JetBackup. JetBackup is by far the best backup software available for cPanel/WHM. I highly recommend it. Shop around, you can find cheap licenses with various providers such as licensepal, licensecube and others.

Good luck!

Another vote for R1soft Backup Manager. It has come a long way since its early years and its definitely a reliable solution, or so we have found.

We rec. cpremote to our customers with cPanel {un managed}
We've used R1soft for quite some time on our corp servers and we also sell this as a backup solution.

I do have to say though : If you have a control panel like cpanel/WHM then cpremote is worth it over Idera. I say this because we've had issues restoring some accounts and data in the past with Idera/R2soft.
