I'm want to understand how NICE decides what data to write to tape.
For the purpose of storing off-site backups, this past Saturday afternoon I changed from "Continuous" Backup Mode, Writing to the Media "Periodically" at: 10 PM Friday night to "Mirroring" Backup Mode, writing and ejecting "Periodically" Tuesday and Friday nights at 9 PM.
Under the "Continuous" method I'd typically end up with one completely full DDS2 tape and another DDS2 with less than 30% used.
Today when I checked the dates of the recordings on both tapes, which indeed "mirrored" and are completely full with only 2% unused, I found only recordings that ranged in date from late July to late August. Naturally, I expected to see recordings from this past Monday and Tuesday. Not good! But I'm not panicing yet. I'm sure Monday and Tuesday's recordings are on the Logger's hard drive since I can query the data. I'm a little nervous right now since my mission critical data didn't show up on the tapes. I wondering what data I'm going to see on Friday night's tapes. Will my mirrored tapes ever catch up?
How does NICE decide what data to write to tape?
