you can buy thumb drives that have built-in encryption. They tend to be expensive but probably the only choice if you want to have secure data on a thumb drive.

Hi<br />
<br />
My client would like to backup his NAS data to external USB pocket drives<br />
<br />
He would also like to encrypt the saved backups<br />
<br />
I haven't found anything that allows this<br />
<br />
I guess I could format the drives with ext3/4 filesystem to limit access to its contents<br />
<br />
Or I could use Cobian with a PC that is on the network to encrypt the backup data<br />
<br />
Any other ideas ?<br />
<br />
thanks<br />

Synology secure backups to USB drive

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Encryption

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
