Adding another VPS to be always up and running
From the beginning, my websites are hosted on a single server. At the start they were hosted on a shared hosting plan but last year I switched to a Virtual Private Server (VPS) so I can have full control over my server and configuration. I decided to do this because I always want to have full control over what I do and because I had multiple problems with the shared hosting (lost of data multiple times). At HostDepartment they are not very professionnal and there servers are slow, they put too many websites and databases on there server. With the VPS I get full control and great performance for about 25$/month, and that is awesome (VPSLand).
Even if now I have my VPS I'm not 100% secure in terms of data loss; the fact is that my VPS got corrupted 2 times and each times all my websites were down 10 days (translated in a loss in traffic and revenue), so recently I decided to buy another VPS to be able to switch from one to another when I detect a problem. Everything is identical between the 2 VPS. To switch from one to another I simply have to change to DNS entries (done by a couple of clicks) to point to the other VPS.
The only thing different between the 2 VPS is the fact that I only backup the data (DB and some specific files and folders) from the first VPS. The other is not backed up because it is only temporary (the time I take to repair the first VPS).
With this solution I will avoid the 10 day down; I can be up and running within 2 hours. Yeah it costs 50$/month instead of 25$/month but overall it covers the oney I lose when the websites are down.
