How long I must keep the binary log?

[Ulises Sandoval]

I need some advice about how long I must keep those long binary logs created by the RDBMS, I read the doc and I understand that those logs are needed in the case of db recovery, since they have all data involved in updates and deletes, they tend to grow to really huge sizes.

I don't use the replication features, so... I think is safe to delete old log files, but how old?, is safe to delete the logs files of the last month or something like that?

Any comment will be greatly appreciated.
