Tape Verification?

I have just started playing with PBS as a long term solution for backing up both my PVE hosts and my separate disks on various hosts.

I've just done a couple of tape writes which went fast and happily, however, is it possible to verify the contents of these tapes to confirm that they are written okay? Essentially a dry run restore I suppose.

Thanks
 
no it's not yet implemented, but i had the same idea a bit ago, but no time yet to implement it ;) would you mind opening an enhancement request on https://bugzilla.proxmox.com so we can keep track ?

edit:

technically there is
Code:
proxmox-tape catalog --scan 1 --force 1

which forces a full read of the tape, but i'm currently unsure if that checks everything we want it to verify (e.g. chunk checksums, etc. )

Is there any progress of this?
To be able to verify the data on tapes is essential.
The least that should be done is adding checksums to the tape chunk files that you can recognize errors.
