Many web hosting companies attracts clients based on their promise of nightly, weekly or monthly back ups of the sites you host with them. These back ups are usually a key selling point for many consumers, who like the security it brings. In the event of a server crash, your site will be protected no matter what, and restoring it should be simple.
Mostly, web host companies back ups are a good thing – they provide stability and allow the website owner to relax. However, these packages do promote laziness; and many a business owner ceases to create their own back up files when they know their web hosting company are doing it too. This is a dangerous trap to get in to; while no one is looking to discourage you from buying a hosting plan that includes back ups by the web hosts, you should be aware of the continued necessity to create your own copies, too.
Web hosting companies are usually reliable. However, in the case of a server crash and you needing to restore your site from nothing, you don’t want to take any chances. You definitely don’t want to discover they have been reneging on their side of the deal, and have not been making back ups, after you’ve lost your site.
There’s no real way to verify your site is being backed up beyond requesting copies of those back ups. Some web hosts will do this, but even if they do, always keep making your own back up copies of your website – without fail.
