Hi,
Please see my question here: https://dba.stackexchange.com/questions/257259/is-it-safe-to-risk-multiple-firebird-nbackup-l Quoting here, but wish you will reply at the site, if acceptable to you. I'm using Firebird 3.0 nbackup to lock + copy + unlock each night. If some steps fail or are skipped e.g. due to system restart (updates), it may happen that the master is not unlocked (-N). Next night, it will already be in locked state, but the scheduled backup task will lock it again (-L). Is this safe? Will the second -L have any effect, or is it a no-op, so a single unlock (-N) will restore it to normal state? Or do I have to safeguard against a second lock (-L) if it's already in locked state? Mvh, Kjell [Non-text portions of this message have been removed]
