Have you ever failed to backup very large files? This article will show you the best way to backup large files.

Backup may fail for large files

While using Windows Backup and Restore tool or other backup software, the backup may not be completed successfully due to too many large files. As the development of digital technology, we have more data, and some of them are very large.

You need to take extra efforts in backing up those large files. Besides image backup, there are more choices that you can backup large files.

Best ways to backup very large files

Redundant array of independent disks (RAID)

You can create a RAID 1, which is like a mirror of the primary drive. If the current hard drive fails, you do need to spend time replacing the failed drive because the Mirrored drive keeps running, leaving no downtime. To do this, you need another hard drive or solid state drive (SSD) with equal or larger capacity.

RAID 1

Anything changes happen on the SSD system drive will also happen on the other drive in real-time. Therefore, RAID 1 will reduce the performance of your SSD. If you cannot take any downtime to your computer and do not care much about the disk performance, then RAID 1 is your best choice.

If you have more hard drives can used for redundant array, you can use RAID 5. RAID 5 needs at least 3 hard drives. The more disks you use in RAID 5, the better performance you have.

RAID 5

RAID 5 not only provides redundant with parity distributed in all disks in the array, but also dramatically increase performance because it allows you to read/write data simultaneously from all the disks in the RAID array.

Backup to external hard drive

If RAID is out of option, then you best choice is image backup. As for backing up data, you should have at least one backup saved at external storage device in case internal hard drive corruption. Therefore, an external hard drive is recommended for backing large files.

As you probably know, Windows built-in Backup and Restore tool will not compress the backup image. Sometimes, the image backup is even large than the source data. For that reason, you may consider free third party backup software AOMEI Backupper Standard.

AOMEI Backupper gives you more options and runs faster.

To backup files and folders with AOMEI Backupper:

1. Free download, install and open this backup tool.

2. Click “Backup” tab, choose “File Backup”.

4. Click "Step 2” to select a location to save backup.

5. Lastly, click “Schedule” to set an auto backup task if needed. If you need choose image compression level, image encryption and other settings, click “Backup Options” button. After that, click “Start Backup” to start the backup.

Besides image file backup, you can also use File Sync to backup large files without imaging. If you want to be able to restore the backup when you cannot access Windows, you can use this tool to make bootable media.

Clone the entire hard drive

If you have a large amount of data, backing up files one by one can take forever. Instead, you can clone the whole hard drive or partition block by block, which is much faster and more stable.

Providing the intuitive interface, AOMEI Backupper allows you clone hard drive to another with a few simple steps.

1. Open this free software.

2. Click on “Disk Clone” under Clone tab.

4. If you want to adjust the partition size on the cloned drive, you can click the button Edit partition size on the destination disk. Click “Start Clone” to start cloning hard drive.

If the source drive is a system drive, the cloned hard drive will remain bootable as well. As you can see, AOMEI Backupper provides different ways to backup large files. Just select your favorite one to protect your files.
