Question How to create a disaster recovery of my files automatically


Hello everybody,

I would like to duplicate a specified directory(A) with its content and move the duplicated directory and content(B) on somewhere else. Whenever I add, delete, update file or directory inside the A, I want B to refresh itself automatically according to the changes in A.

In short, A and B will have the same file and folder structure and content whenever I want to achieve them.

I know this is twice slower but I will use this procedure in order to create a hot backup.

Any suggestion will be appreciated,

rsync

The initial run does a full copy. Subsequent runs very efficiently just copy the differences. Run it off cron.
