strange acceleator behavior ?
Hello, I'm working with a new netbackup installation, and I'm having difficulties understanding how the accelerator works in the specific case I have. The client system is an AIX 7.1 server, and we are backing up only a file system that contains Oracle dump files. Oracle is dumping the database every day at 6 a.m., and before that, all previous dump files are deleted. In my eyes, every day the files are new, and I can see that from the timestamp. The [dump files are 5TB total The initial backup took 15 hours. The second backup took 3 minutes with 99% acceleration. I know that the files are almost the same as the previous ones, but I cannot understand how Accelerator knows that.

Client-side deduplication cannot be used because the deduplication ports are closed. We will open them later. We are using a flex appliance with master, media, and worm storage roles. The Netbackup version is 10.1.1.
