Typically, I’d do this programmatically from within the application without giving it a second thought, wrapping up in an SQL statement and firing it over.Recently, while doing some development work for one of my clients, I was given the requirement to add Created and Modified timestamps to a whole bunch of existing data tables.Thankfully, a couple of My SQL’s internal features came to the rescue.Adding a modified timestamp to a table is the most straight forward.
Of the track I recently found one good option for backup (fresh install) of a system which contains lot of customised packages, we can use the “Ghost for linux”.
Some of the additional features of rsync are: Rsync copies files either to or from a remote host, or locally on the current host (it does not support copying files between two remote hosts).
The rsync remote-update protocol allows rsync to transfer just the differences between two sets of files across the network connection, using an efficient checksum-search algorithm described in the technical report that accompanies this package.
It is released under version 3 of the GNU General Public License.
An rsync process operates by communicating with another rsync process, a sender and a receiver.
