I am currently in the process of writing a backup plan for the webserver in use by my business. I am very new to this area and have a few ideas about how things should work but am unsure of what tools to use and what sort of restore process is appropriate.
I'm looking for something relatively simplistic and it doesn't have to be 100% paranoid just enough to give me a reliable backup. Speed is not of the essence and there is not going to be a live fallback in place.
The backup will be onto a single hdd that will be stored onsite (no option for offsite as yet).
Backups will be taking place weekly.
I am constrained by both time and money which is why I'm aiming for a good enough solution.
Is taking an image of the webserver system drive periodically and using that as the backup appropriate?
Should I be testing that the backups restore correctly every time that I perform one?
This is a bit broad but what setup would you use if you were in my place, given the services I am running? Should I add additonal machines and split the services?
Any advice is much appreciated!
See below for server details
- Linux Ubuntu server
- single 500gb sata drive
- Single machine behind router (with firewall) accessible to the internet.
Based off the answers here and in the interest of not being too dodgy I have landed on the following plan of action.
- RAID 1 // makes sense and the consensus is it would be unwise not to
- Separate backup box with rsnapshot for continuous backup
- Weekly images on external HDD just in case
- Offsite backup // haven't found a vendor yet and will worry about this later
Thanks for the help from everyone!
