OP is looking for a set-and-forget backup solution for the replacement for a 7 year old XPS. While many in this thread offering expertise are familiar with all sorts of advanced concepts - NAS, RAID, bare metal restore - and for whom a robust strategy of local and offsite backups is pertinent, consider your audience. I too back up locally with 24TB of drives on site, to CrashPlan, and to Amazon S3 with replication across three regions. I would never suggest that for the typical user. Keep it simple. CrashPlan subscription to back up to the cloud in case the house burns down. If you've got lots of data and need to restore all of it quicker than the internet allows if something goes wrong, then plug in an external hard drive and let CrashPlan back up to that too.
