Push pnfs files to tape #28

Open beauremus opened 3 years ago

beauremus commented 3 years ago

We need a tape backup strategy. Yujun Wu will be a good resource.

We had it on tape all along. This is good, but also raises the complication that files not touched recently may need to be explicitly re-staged to become readable. Yujun Wu should be able to find out the policy in place for removing files from cache, and can tell us the commands available for re-staging if needed.

I'm not sure I fully understand the processes between cache and tape. Do you think we are ok until we need to read old files? I wonder what Rsync will see for files, not in cache. My guess is that if Rsync is set up not to delete files then we're ok 🤷🏻 ?
