Hello,.. frequently i need to do backup so i choose cron to do so (just a tar command). but most of the time it is the file wasn't changed so i search for a way that a backup will be insiated by a change to file (touch). at first i thought about a program that will cheack the status of the file (stat()) and if the info had been changed then it till backup it . then i realized that i can't work like that (since you never now when excatly it has been done) and more to be effective you need to do lots of read calls.
i googled and found inotify (not sure that is the right solution). will it be called on a change or it will be just as any other deamon that runs in the memory . anyway if it is working only when data is changed then is there a program that will be called (like im asking in this mail). thnx in advance
