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? Or is it better to install it on another networked pc and do it through the network? Whichever is more reliably/consistently connected or available for doing backups. 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@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx
