Can tar files be verified once backed up to LTO5

[linuxgabe]

I am trying to find a terminal command to verify tar LTO backup files. I am backing up large media files using Ubuntu and LTO5 drives. I would like to be able to verify "file sizes" or even "number of items" on the backed up tapes. I don't know if you can even do that. Just wondering because I am fearful of losing an media. Any help would be appreciated.
Thanks

"tar tvf device_name" will list the files in tar archive without restoring them

"tar tvf device_name" will list the files in tar archive without restoring them

What i'm mainly looking for are the File Sizes or number of items in the Files

Any cmd for that?

the tar command gives you the file size of every file.
tar tvf tarfile | wc -l
returns the total number of files in the archive
