"Due to potential legal incompatibilities between the CDDL and GPL, despite both being OSI-approved free software licenses which comply with DFSG, ZFS development is not supported by the Linux kernel"
@mcc been that way for decades now
@whitequark I have a new hard drive I intend to use primarily for backup and I am currently considering BTRFS or ZFS for the Linux part instead of ext4 (because I hear they can do some thing of storing extra error-checking data to protect against physical disk corruption). In your view, if I intend to use mainline Debian indefinitely, will BTRFS, ZFS, both, or neither give me the least pain getting things working?
@mcc @whitequark just my take but I consider ZFS aimed at arrays and such. Single drive I’m just not sure you’re going to get any benefit and it might actually be substantial worse.
@petrillic @whitequark do you think there is an advantage of BTRFS over ext4 for a single drive, single computer, non RAID, my sole/primary goal is "i want it to last as long in a room-temperature drawer as possible"?

@mcc @petrillic @whitequark btrfs will allow you multiple copies of your data and metadata on a single disk.

It might protect against some disk issues, but probably not that many. SSDs will just stop working altogether on controller or dram failure and lose all of the disk at once.

I hope you are aware that SSDs are not recommended to be kept unpowered - the 10 year data retention relies on scrubbing that happens only when the power is on.
