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.
- Question from Acronis Forum
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.
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.
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.
To create a scheduled backup plan using Windows' built-in Backup and Restore tool, you can follow these steps:
Files that have changed or were newly created since your last backup will be included in your backup, based on the schedule you have set.
If you're not familiar with Windows' built-in backup tool, using it might lead to backup failures. A better approach is to use a different method that's easier and safer.
Qiling Disk Master Standard is a professional backup and restore software for Windows editions, allowing free full and incremental backups, and advanced differential backup, with an option to copy only new or modified files.
To backup only new files to an external hard drive, you can use Qiling Disk Master Standard. First, download and install the software on your computer. If you're a server user, you may want to try Qiling Disk Master Server instead. With Qiling Disk Master Standard, you can easily backup new files to your external hard drive, making it a convenient tool for maintaining your digital files.
Step 1. Connect your external hard drive with computer and make sure it can be accessible.
Step 2. Launch this freeware, click Backup -> File Backup.
Step 3. Select "Files" or "Folder" that you want to backup.
Step 4. To store the file backup image, click the box below the arrow and select the connected external hard drive as the storage location, or choose to store it on a local drive, cloud drive, NAS device, or USB drive.
Step 5. To schedule a backup, click "Schedule Backup" in the lower left corner of the program. In the pop-up window, you can set the backup schedule to daily, weekly, monthly, or event triggers, and even USB plug-in.
Step 6. The backup scheme is set to incremental by default, which means only new or changed files will be backed up. Click OK to proceed.
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.
You can easily backup only new files to an external hard drive in two ways. The first method is to use the backup software that comes with Windows, but a simpler and more suitable option for novices is to use a professional backup tool like Qiling Disk Master.
You can use File Sync to easily sync changed files from the source directory to the destination directory. Additionally, if you're experiencing the OneDrive sync pending problem, this software can help you solve it.
