Can I back up my files directly from my desktop/laptop computer?

No, only data stored on a Synology NAS can be backed up directly to Synology C2 using Hyper Backup. However, you can back up your devices to Synology NAS using any Synology backup solution. Hyper Backup can then be used to store an offsite copy of files on your Synology NAS to Synology C2 Backup.

Can I back up files from multiple Synology NAS to C2 Backup?

How long does the first full backup take?

Synology therefore cannot predict with certainty how long your first backup will take. At an upload speed of 20 Mbps, it might take 3 days to transfer about 500 GB of data.
