Recently LinuxQuestions.org held a poll to determine the 2015 favorites for many applications and/or services. One of those was for backup (and I hope restore!). See
http://www.linuxquestions.org/questions/2015-linuxquestions-org-members-choice-awards-117/backup-application-of-the-year-4175562726/I did not vote, because most of what I saw was a complete unknown to me - and the winner (
rsync) - which I do know
somewhat does not feel like a backup/restore solution compareable with mksysb (for rootvg) or savevg for other volumn groups.
So, not going to start a poll - but am very interested in what you use, or think to start using for your backup/restore of your (bare metal) Linux systems/virtual machines!
Maybe you will convince me that
rsync is the, or at least 'a', way to go!
