I have to write a script to take differential backup (of a directory). Differential backup:
A differential backup backs up only the files that changed since the last full back. For example, suppose you do a full backup on Sunday. On Monday you back up only the files that changed since Sunday, on Tuesday you back up only the files that changed since Sunday, and so on until the next full backup.
Suppose for Example:
Monday - Performed a full backup and save the file set.
Thursday - Want to Perform a differential backup using the same file set. All files that have changed since the full backup are backed up in the differential backup.
From now on, if I require I will use the script so please suggest to proceed or how to write the script to automate this.
