Good question. Did you exclude anything from the Time Machine backup? Read Exclude files from a Time Machine backup on Mac - Apple Support. The example they site (system files) is a particularly bad choice in my opinion so don't do that.
I've checked that but no I didn't exclude anything apart from another attached hard disk i didn't want backed up.
Next question: are your Contacts stored "On My Mac" or in iCloud? If it's the latter you can restore automatically created backups of Contacts. To do that, log into iCloud.com using your Apple ID, select Settings, and scroll down to Restore Contacts. It's all the way at the bottom under Advanced.
They're stored in iCloud. I found that I had to restore all my contacts from iCloud but it would do a backup before doing the restore. What I did then was the full restore, took note of the missing data from the one contract I was interested in, restored from the backup it had just made then corrected the details of that contract.
Many thanks for your help.
