Hello everyone!
My manager just brought to my attention that this organization has a CentOS 6.3 server - he didn’t specify what it’s hosting just yet but asked that I find a solution to do a full backup so that we may restore later onto bare metal with the option to migrate from CentOS to another Linux distro.
Has anyone had experience with backing up / restoring CentOS 6? And if you know what would be the best Linux distro to replace CentOS 6? Or even a step by step guide for both or either one?
Please and thanks in advance!
I have a CentOS 6.8 server that I backup with:
dd if=/dev/sda of=/dev/sdb conv=sync,noerror bs=4M
Of course change the sda/sdb to whatever your source(backup drives are
Wow… that’s nice and clean - straight forward.
Thank you!
Note: do that from a live CD/USB or with the source drive mounted readonly. If you dd a mounted and used filesystem, you’ll most likely end up with a corrupted and useless filesystem on the target.
Nice! Thanks for the tip!
