The main storage ("media" partition of ~450GB hosted on a DL380G7 with a DS4243 array (mdadm/lvm) "under the stairs") is kept in sync (using rsnapshot) with a secondary storage (SS4200 with an external eSATA enclosure) in another building on the farm - but hosted on the same electrical branch and connected to the same physical network so it is vulnerable to any spikes which make it past the quite elaborate power filtering I installed when I got fed up with repairing or replacing hardware after every thunderstorm. There is a separate backup to a set of spare drives on the DS4243 meant for quick access, e.g. when some experiment has gone wrong. Separate from this I make encrypted regular backups to online file hosting services (currently using free accounts on Mega) as well as to storage hosted by family abroad. I've given up on making backups on DVD a long time ago since this was simply too much work for the relatively small benefits. The chance of all of these versions becoming unavailable is low enough for me not to worry. If I end up under a tree some day nothing changes in the short term, the data will be available to those who have not yet met their tree. In the longer term I'd expect someone to either pick up where I left off or move the data to some storage which befits their level of expertise and needs. I don't want to force them into any contract with any provider, nor can I decide what they deem to be worth keeping.
