Hdd With Badblocks And Btsync

Recommended Posts



It depends if bad-block is detected by OS or not. If EDC did not detect corrupt data (and the OS API simply returns corrupt file piece) - sync will recalculate hash and  propagate corrupt data.


If OS detected the error - it will fail the file read API and sync won't have access to the damaged piece of file, so it won't propagate.

So more nodes you have = more probability to lose your data :(


More correctly: the more RW nodes you have. If you stick to RO nodes for backup, this won't be a problem.


Bit-rot is a problem that needs to be addressed at several levels, unfortunately (but understandably), most filesystems ignore this issue and shift it to hardware, which often also skips checksum checks due to performance issues.
