EX 4100 Backup Options?

New to this device and looking for feedback on backup options:

USB Backup
o I have it set to sync to an external MyBook. If I set it to copy, will all new files and versions be copied to the external drive?

o There is supposed to be an Incremental option but it doesn’t appear on this NAS. It’s got two drives configured as mirrors with two bays open.

Cloud Backup
o I’d like to configure cloud backup and would like feedback/advice on the Elephant Drive and Amazon S3. Which is recommended? Most important is to be able to restore from a date certain in event of ransomware infection.



These are the results of my testing USB backup because I had a similar question. I knew I didn’t want incremental because I didn’t want all these versions.
