Is there any script for linux which can backup the home directories and mysql databases in separate directories . i mean best of all scripts which is general and any one can use that one.
By backup i mean , i just to makr tar.gz and copy to separate directories
Something which uses all sort of advacned command which are not commonly used but perfect
If all you are looking for is a decent backup script, check out my site as I wrote up a how-to on this a few weeks back.
