If just a single or few bits flip in a disk sector / flash block, wouldn't that be either corrected by the device's ECC mechanisms (thus be no problem) or...

@enkore yes, aborting is not that helpful - open a separate ticket for it.

Correct, a mirror doesn't help for all cases. But for many cases, it for sure can. The disk controller generates and stores own CRC / ECC codes additional to the...

@FelixSchwarz thanks for the pointer, I just reviewed that PR. But as @enkore already pointed out, we rather won't extend 1.2 scope, there is already a lot to do. Also,...

@gour If we find a good way to implement it (that does not have the mentioned issues); I guess we would consider implementing it. There is the quite fundamental issue...

@StefanBertels having stuff in multiple repos (at different places) is always a good idea. It can't work with encrypted repos **on chunk level** as different encryption keys also means differently...

@spikebike the manifest needs to be written at the end, so guess what would happen if you simply write it twice, after everything else? It would maybe make you feel...

Until someone convinces me otherwise, i think that it is pointless to add error correction in borg (see some of my previous comments). Adding it might just create false hopes...
