What to do when archive logs are lost/corrupted that are not backed up All recently generated archive logs were corrupted but datafiles are fine.What if recently generated archives corrupted and the archives backup is not available, so what would be the strategy to resolve the issue and is there any possible way to rectify the archive log corruption.
As soon as your recovery thread is interrupted, making it impossible to recover from an earlier backup to the current time, the remedy is to take a backup before something more serious happens.

Next investigate how the archives became corrupted and solve that.

Backups are of no importance, important is the ability to recover from a disaster and for that backups or physical standby databases can be very convenient to have.
