Time Machine couldn’t complete the backup to “Time Capsule 3TB”.

Hello Team,

apologies upfront in being unable to solve myself.

i keep getting this error message on my iMac (Mams)

The backup disk image “/Volumes/Angus/Mams.sparsebundle” is already in use

i keep getting this error message on my MacAir (Coddled'sAir)

The backup disk image “/Volumes/Angus/Coddled'sAir.sparsebundle” is already in use

i keep getting this error message on my MB Pro (Coddled'sMBPro)

The backup disk image “/Volumes/Angus/.Coddled'sMBPro.sparsebundle” is already in use

have been unable to back up for two weeks now.

any advice that solves this would be gratefully appreciated.

best
