The machine is a mid-2012 MacMini that operates as a server (colocated in a distant knowledge heart).
The MacMini has an exterior USB arduous drive to supply backup storage (WD Components Transportable 2TB, USB powered)
Each night time the startup quantity (inner SSD) is backed as much as the exterior drive utilizing the applying Carbon Copy Cloner (with automated job).
From the duty historical past I can see the bakcup usually takes round 30 minutes.
The final backup took 1h 45m.
Regardless of no error have been reported by CCC, I’m questioning:
- what might have prompted that?
- is it a sign of imminent failure?
- what instruments might I exploit to analyze the problem?
I do know for certain that:
the problem is with the exterior HDD not the inner SSD (as a result of the HDD is subsequently backed as much as a distant mac and in addition this operation did take for much longer)
the HDD shouldn’t be full (about 50% obtainable)
there may be nearly no load/exercise on the server because the nackup takaes place at late night time when nobody use the server
