Safe way to backup an RDB file
teleo
In Mongo, to backup the database it is possible to lock the slave,
copy the files and then unlock the slave.

What is the safest way to backup an RDB file in Redis?
Thanks,

In Redis .rdb files can be copied while the server is running without
any need of lock. No corruption is possible since the new file is
always saved in a temp location and atomically rename(2)d to the new
location.
So just use "cp" :)

Just to clarify, what happens if while I am copying the RDB file, a
new file is renamed to overwrite the RDB? Isn't it possible that the
disk space formerly occupied by the old RDB will be reclaimed and used
by some other process? Or is it the case that while the file is open
by me, the space will not be reclaimed?

proper way to backup a Redis instance that is using AOF rather than
snapshotting. Do I still need to do a snapshot for a backup, or can I
just copy the AOF file?
Thanks,
David
