If you turn on FILE encryption - the data will be encrypted on the tape and on the network. If you turn on TLS encryption - the data will be encrypted on the network but NOT on the tape. If you turn both options "on" the essentially data will be encrypted twice on the "network" and once on the tape

[Bacula-users] Encryption and hardware compression

2007-10-26 Thread Eric Böse-Wolf
Hello Bacula Users, I want to do encrypted backups and asked myself wether it makes sense to turn off the hardware compression of the tape drive. AFAIK does encryption do some kind of compression (the entropy of the messages is significantly reduced) and so an additional hardware compression c
