Hi! I see no issues against uses btrfs send/receive or rsync as backup from SSD to HDD. With btrfs send/receive I think after the initial sync it can even work quickly enough to have it run every 10 minutes or so. But if RAID allows write-mostly, why not. I think BTRFS RAID does not (yet). Am

Backups are usually supposed to be done on a different storage device than the one that is actively used. I wouldn't include the "backup scenario" here unless Jos is doing backups of a storage device onto the storage device itself (if that is the case I would strongly recommend NOT to do that). As

Doing regular backups takes pretty good care of device failure. Depending on how it is done, it also can help recover from accidents other than equipment failure, like deleting files in error. That said, I have read that for some time SSD reliability has been at least on a par with HDDs. And you

Keeping everything on the SSD has its advantage too - speed. But won't secure the data on the fly as keeping it on the HDD. Actually I'm confused which method to follow. Both has its own advantage and disadvantage. On 06-Feb-2016 7:54 PM, "Bennett Piater" wrote: > I just keep everything on my ss

I have to agree with Aleksandar. The SSD is the place that you need to put the OS, software that is used regularly, and under some circumstances temporary large datasets that are being used repetitively during a working problem ( ie stacking.) Your home partition, and mundane data should be moved
