Subject: 40m files backup situation 

The 4TB HGST drives have arrived. I've started the FB1 dd backup process. Should take a day or so.

Quote:
Edit: unmounting /frames won't help, since dd makes a bit for bit copy of the drive being cloned. So we need a drive with size that is >= that of the drive we are trying to clone. On FB1, this is /dev/sda, which has a size of 2TB. The HGST drive we got has an advertised size of 2TB, but looks like actually only 1.8TB is available. So I think we need to order a 4TB drive.
