Alexandre Kouznetsov:
Thank you for that excellent answer.
I'll add the files in that directory to our daily purge script.

It looks like pve backup puts a file to /etc/lvm/archive for each
snapshot back up. The not too hard to figure out clue is this line:
description = "Created *before* executing 'lvremove -f
/dev/pve/vzsnap-dell-1-ib-0'"
Actually, it's not PVE who puts the backups there, but LVM tool set itself.
Not on snapshot but on lvremove event, done over snapshot or a regular volume.
Very handful, saved my ass a couple of times.
My question - are those auto purged ?
Yes, after 30 days as default.
In my case, in one of my servers with LVM storage I observe 2040 files under
/etc/lvm/archive (I do lot of snapshots daily as part of the backup process
and delete them almost immediately). The oldest ones are from 2013-10-01.

3.4. Logical Volume Backup
"Metadata backups and archives are automatically created on every volume group
and logical volume configuration change unless disabled in the lvm.conf file.
By default, the metadata backup is stored in the /etc/lvm/backup file and the
metadata archives are stored in the /etc/lvm/archive file. How long the the
metadata archives stored in the /etc/lvm/archive file are kept and how many
archive files are kept is determined by parameters you can set in the lvm.conf
file. A daily system backup should include the contents of the /etc/lvm
directory in the backup. "
