If you care about the data at all, then B is the top priority. > If case B, should I get a USB3.0 adapter or similar so that I could just plug > the HDD, let it do the backup and unplug and store it?

The network solution is a bit more complicated, but overall I find it more convenient. USB enclosures are notoriously flaky with the myriad bridge chipsets floating about; and even name brand USB bus support doesn't help. I advise getting a good USB hub. Don't expect that a direct connection between USB drive enclosure and the computer provides a more reliable connection. I have a dyconn USB hub with a power supply providing 2.5A, which for a 4-port hub. If you look at the specs for laptop hard drives, all want upwards of 1A for spinup and around 0.35A during use. So there's a power aspect to making sure the drives have the power they need, without wigging out, and there's a data stream rewrite aspect to the hub that in a sense "cleans up" the flaky communication between host and device. -- Chris Murphy _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
