Full database w:backup performed
2013-09-02 Howto make cheap and easy backups on Linux?
To properly do a backup one must:
- ) Isolate the information objects that need to be successfully backupped and do it
- Usually the full home-directory and a full dump of w:databases is all you need
- Use a dedicated backup directory on every machine. I call mine /backupmedia. The main point is that it needs to be somewhere outside the directories you are interested in backupping
- ) VERIFY THE BACKUPS TO WORK BY LOADING INTO A REFERENCE SYSTEM ON NON-PRODUCTION CLOSED SERVER INSTANCE. Not verified truly cannot be called backup because if they are found to be faulty shit will ensue. Check that the .tar.gz's unpack and that the database dumps can be read onto MySQL.
- ) Criss-cross-copy from every machine to every machine / distribute the backups to as many servers, laptops and USB sticks as possible.
- This way we can just substitute /media/usb0 to make the off-line copies with command 'sudo cp -r /backupmedia/* /media/usb0/.' or 'cp -rf /backupmedia/* /media/usb0/.' if you don't need to force using sudo rights which I do for some reason on the w:USB stick. Be adviced that a normal USB key will accept any sudo password on any machine afaik.
