Usually but it depends on the compression scheme. There’s usually a “window” of how far back they look, so they can resync after a while, but it’s unlikely and the offsets will likely have changed so you need to handle that. You can force this property by introducing synchronisation points though, gzip has an `—-rsyncable` which makes that a lot more likely, at a small compression cost. Edit: apparently zstd has also had —-rsyncable for the last 5 years.
