If the drive is used for data storage and does not contain any system files, running fsck file system check is just a time-sink
I suggest edit /etc/fstab
sudo nano +10:77 /etc/fstab
and change the final number 2 to 0 to disable fsck:
UUID=cc1265a1-3a30-4626-8605-ccf1db077266 /data ext4 defaults 0 0
is it possible when it hasnt made a backup today it makes one when I turn my pc on, hence the 5 min delay?
Data in OP shows fsck causing a 5 minute delay
If you deal with the known issue first then any other delay issue will be easier to spot
