time machine backups: usb drive for use on synology router
Hello, I've tried repeatedly to get a time machine backup on a laCie hard drive attached to a Synology router (RT2600ac). I was told by Synology that the laCie drive isn't compatible with their router. For those who have this or similar Synology routers, is there a hard drive for drive type/form factor that's worked well for your for running Time Machine backups?
Some details: The first couple backups (partial) using Time Machine succeed and data was initially transferred. But subsequent backups were excruciatingly slow and never completed. Thereafter, it was stuck in "preparing" status before failing. Synology referred me to their list of supported drives but I'd rather get a recommendation before choosing one at random.
