I have two situations I need some clarification.
1) Let's say I made a backup of all the MySQL binary logs before I purged a single binary log file (the oldest one, possibly the very first one).
Can I restore this single binary log from the backup I made? Just copy and paste it from my backup to the MySQL data directory and I can use it again as if it was never deleted in the first place?
2) Another situation, let's say I purged every bin log except the current one but after a month or two I needed to restore something from the middle of the purged bin logs like:
Can I just restore this single file from backup and do whatever it is I need to get back from this bin single bin log file? Or I would need to restore everything before I could use that file?
