The Safest Way to Backup your Data
Copy and Data verification
Takes 14 minutes to "Copy&Verify"data by a 32GB CF card (Copying in 7 minutes and verifying in 7 minutes)
After all files are copied successfully, ND2901 will automatically compare data on the internal disk and the memory card for full verification.
Viewing file information and previewing photos on internal disk
In the PREVIEW, you can quickly verify the backed up files by your eye.
Creating a secondary copy to a USB drive (SYNC)
Copying all files stored on the internal disk to a USB drive
Incremental copy is supported, only files or folders that have changed since the last backup will be copied to increase data sync speed.
Viewing file information and previewing photos on an external USB drive
Select the external drive (External DEV) in the PREVIEW then plug-in a USB drive. You can quickly verify the backed up files by your eye.
Erasing the memory card
Two separate drives will not fail at the same time. It will be safe to delete data from your memory card.
