How to backup .aof file ?

[Favo Yang]

Is that safe to just cp .aof file for backup ?

[Konstantin Merenkov]

It should be safe to do so. It will be consistent. We tried to cp aof
under load and try to start redis from every aof copy, worked fine,
never broke.
I hope that it will be confirm by someone else because, well, I just
figured it out myself.

Hello, it is indeed safe.

At max what may happen is that the resulting file contains non well
finished data, but to fix it all it's needed is to run redis-check-aof
--fix if Redis will complain on reload.

Cheers,
Salvatore

Then it's better either add a dump_aof command or add
BgrewriteaofCommand a parameter don't delete the old file, we can
trust the old file as an aof dump.
