Need to Backup Only Newer or Changed Files to External Hard Drive

Backup only for files newer than a certain date?

You can use the `--since` option with the `rsync` command to backup only files that are newer than a certain date. For example, to backup files that are newer than 2 days ago, you can use the command `rsync -avz --since=2d /source/folder/ /destination/folder/`. This will only copy files that have been modified in the last 2 days. You can adjust the time period by changing the number after `--since`, e.g. `--since=1w` for 1 week or `--since=1m` for 1 month.

To save only the files that are newer than the most recent full backup, you can use the "robocopy" command in Windows, or the "rsync" command in Linux/macOS. Both commands can compare the timestamps of files on both drives and copy only the newer ones. For example, you can use the following command in Windows: `robocopy "D:\Source" "D:\Destination" /mov /minage:2023-03-01` (replace "D:\Source" and "D:\Destination" with your actual drive paths, and "2023-03-01" with the date of your most recent full backup). This will move all files from the source drive to the destination drive that are newer than March 1st, 2023.

You can only backup new or changed files to an external hard drive in Windows, which can save time and disk space. There are two methods to achieve this.

How to Backup Only New Files to External Hard Drive

How Do I Backup Only New or Changed Files in Windows 10

To backup only new files to an external hard drive, you'll need to understand some basic backup methods, such as full backup, incremental backup, or differential backup. This will help you determine the best approach for your specific needs. Once you've chosen a method, you can proceed with the backup process, ensuring that only new files are copied to the external hard drive.

A full backup is a complete backup of all files on a designated hard drive, requiring a larger disk capacity and being time-consuming, but providing the best protection, serving as the basis for incremental and differential backups.

An incremental backup is a backup of all changed files since the last full or incremental backup, requiring less time and storage space than a full backup.

Incremental Backup

Differential backup stores only new or changed files since the last full backup, providing high security, using less time and storage space.

If you want to backup only new or changed files in Windows 10, you can try the incremental or differential backup method, which will copy only new files to an external hard drive.

Copy Only New or Modified Files with Backup and Restore (Windows 7)

To create a scheduled backup plan using Windows' built-in Backup and Restore tool, you can follow these steps:

  1. Connect the external hard drive to the computer where you want to store your backup, ensuring it has sufficient storage space.
  2. Press the Windows key + S, type "Control Panel" in the search box, and click the top result to open the Control Panel.

More options (only supported in Professional or higher editions):
★ Differential BackupThis script will create a backup of changed files based on the last full backup, eliminating the need for multiple full backups and differential backups. It simplifies the backup process to just one full backup and any subsequent differential backups.
Enable Automatic Backup Cleanup: The old backup will be automatically deleted to free up disk space. You have three options: the easiest one is by quantity, while the safest is by daily/weekly/monthly, which saves the latest incremental or differential backup and all full backups.

Step 7. To launch the daily schedule backup, click Proceed after setting up the daily schedule backup to backup new or changed files.
