I had an 80% usage warning come up this morning on my ReadyNAS Duo.
Time Macine backs up to a single 1Tb drive. the drive has no shares set up on it.
The second drive has shares for other use.
Am I right in saying that Time Machine will reach a point where it simply overwrites earlier backups and the drive will stay as full as is safe for it to operate?
When you use Time Machine backup in your ReadyNAS, it will ask you to allocate space that will be used to backup your files from your MAC computer. You don't need to worry about your volume because Time Machine automatically deletes the oldest backup from the day it started to backup files. For more information, kindly check this article.
It was one of those things I set up once and forgot. I do recall choosing 900+gb as a limit.
as an aside, I really needed the backup a few days later as I had to do complete restore of Yosemite OS when El Capitan failed.
The bad news was that the Mac migration assistant software found the backup but wouldn't load it.
I had to go through finder and drag and drop from the backup
One further question (which may be better aimed at Mac users). I now have to set up time machine again. will it recognise that an earlier backup exist and carry on from there or will it ignore it and overwrite it
