Time Machine problem

Had my iMac HD crash and was replaced. Went to do a restore from my TM and noticed the last backup was April. Yikes. Can't believe April till July was not listed.

I did the April restore as a best effort. Went into TM using disk until , it listed a few problems which it repaired. Tried rebooting both imac and TM. TM did a usual current backup . So far still missing those months.

Note I am using time machine to back up to time capsule

Anyone know anything I could do to check to see if those missing months might somehow be still there and salvageable.

Thanks.

 

lil help?

Really in a bind was hoping that there might be at least one helpful response? Anyone encounter something like this? Is there nothing to check?

thanks
