These are two different things with different objectives. RAID is not a backup solution, it's a data-loss recovery solution (i.e. for hardware- related problems). If you accidentally delete an important file, RAID in itself is not going to help you recover it (though it might if you have a journalled filesystem and take regular snapshots), but a backup will do that if it's configured properly. > 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?

I use a NAS on my LAN, but it's an old machine with only 100Mbps Ethernet and an obsolete version of Debian. I don't want to buy a new NAS so I'm seriously thinking of just using a local disk, which would also be easier to configure. Your preferred backup software may be important, e.g. s/w that assumes the backup is on a directly-accesible filesystem can really hammer your network if you just mount the remote drive with NFS, even if it's just verifying that nothing has changed. > Is there a better, easier, less troublesome option to keep the data safe > that does not involve the cloud? You need to give more detail of your exact requirements, e.g. how much data? How often do you want to back it up? How long do you want to keep it? Are you backing up multiple machines or just one? If the former, are some of these running Windows or other non-Linux software? poc _______________________________________________ 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
