Backup Data Using Date and Time Stamp
One of the very useful feature is copying files according to their date and time stamp. While we are making backups regularly we can specify time which files those are changed specified time to backup. For example we take backup in following periodic dates.
We can specify date where we will only copy files changed after that time. In this example only files those changed after 15-04-2017 will be copied.
$ xcopy \project \project-backup /d:15-04-2017
Other useful feature is printing files during copy operation. This will give us feedback about the copy operation. We will use
/f option for this.
$ xcopy /f Downloads Downloads-backup
Copy Only Files Existing Destination
While copying files from source to the destination we can set a rule which will only copy the files existing in remote destination.
$ xcopy /u Downloads Downloads-backup

Windows have different type of files attributed like
Hidden . These files especially used by operating system or related applications. These files are not copied by default. In order to copy these type of files we will provide

We will create a file which stores file names and extensions line by line those will be excluded. We have a file
ex.txt which have following contents.
