I'm using Networker 7.3.2. I am doing a backup to disk and then cloning to tape. The tape I'm writing to is a SDLT600 inside an ADIC Scalar 24. The write speed is 30 MB/s. It's putting about 375G on each tape. The mt command shows compression is enabled. But...

The Scaler 24's front panel has an icon that is visible when hardware compression is turned on. During the clone operation this icon is NOT on. According to ADIC support site, this icon should be visible if hardware compression is working. If not, it may be a backup software problem...


Does anyone have any thoughts on whether compression is or is not working here or has anyone seen this with a Scalar 24?
