I've got a running system here but upon setup of the box I did not think about founding it all on a redundancy solution of some sort, first choice would have been a RAID 1. Anyway, now I am here with the problem that my main drive might fail any time.
Moving data to a temp location, re-setting-up the system, and moving data back is *currently* no option. But installing another harddrive and mirroring all data as a sort of "near RAID 1" would be an option.
No, what technique would you recommend to copy or clone my main drive? I could think of a near-realtime solution, with a cron, let's say every 20 minutes, to copy/identify new data. But what tool can help me with that?
And- is there a way to exactly clone the drive, including bootrecords etc. so in a case of failure of drive 1, I just need to switch cables over to drive 2? Is there a way to do it incrementally, so the clone process doesn't start from scratch each time (peformance!)
Any hints and tool recommendations welcome!
The solutions will vary based on your computer's type, OS, and application.
I recently used Acronis MigrateEasy to clone a drive - but that's Windows, and I don't know that it supports Unix/Linux. It works perfectly. Definitely not a Mac software.
