I currently use btrfs on almost all my server and offline backup drives mainly because of the ability to transparently compress files to save space. But apparently btrfs can get corrupted if it unexpectedly loses power? Is there a more robust and corruption resistant filesystem that you’d recommend that also has the ability to compress files?
If you’re using consumer HDD’s or SSD’s then they themselves can get corrupted in power failures, so the software almost doesn’t matter. Better use a UPS.
