restore failed: reading file "/backupserver/setup02/.chunks/5330/53302daee7a748f23e2104967dd7dceabcc61c7d1ad7f069386e513ea3a821bb" failed: No such file or directory (os error 2)

the chunk is missing, so either you can restore it by syncing the snapshot again from another pbs/tape backup or it gets reuploaded when you do another backup
when both is not working, you can try to use the 'proxmox-backup-debug' tool to restore the images with '--ignore-missing-chunks' but this only replaces the missing chunks with zeroes,
so the data may be corrupt

otherwise there is no way to restore deleted chunks

HI.

Thank you for the response and the update,

I have checked the chunks are available, but still, the backup is not restored and throwing this error,

anyhow now I have created another datastore and it is getting restored.

Thanks & Regards
