A current motherboard will typically have 4 SATA ports, so unless you have a lot of disks, optical drives, etc., you will probably have an available SATA port. If the solution is SCSI, you will probably need an add-in SCSI card. Your power supply will also need to be sufficient for providing power to the additions.

If you have protection against fire and so on, you are protected against deletion (for files that are actually backed-up) and disk failure. If you are protected against disk failure, you are protected against deletion (for files that are actually backed-up). There are trade-offs involved. Protecting against deletion is relatively simple, fast, and inexpensive, but also may require more discipline on your part (making sure you run a "backup" after creating a file and before potentially deleting it). As an example, if you want to protect source code for programs you write, you can use "git" or pretty much any "revision control system". You've been focused on speed, but speed = $$, and you also said "I've very rarely needed these capabilities". You should consider how much speed you actually *need*. As someone else mentioned backups are typically scheduled to run overnight, or some other time when the system is idle, and it doesn't really matter if the backup takes 5 minutes or an hour. This also assumes you leave the system up-and-running overnight; if you need to conserve power the cost of "speed" may be valuable. -- _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] 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/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
