I have never used Linux LVM, but the error message makes sense. You have used dd to clone your disk. dd actually copies everything from the input to the output. In the case of your disk, that includes things like PV information that pvcreate would store on the disk (disk id, maybe host id and such). So you are getting a conflict.

Instead of using dd to clone your disk, use dump or tar or something similar. This will just copy the files and nothing else. If you are determined to use dd, then you cannot mount the disk to for any incremental backups. Just use dd to do a clone once a week or so. Incremental backups during the week can be taken on another hdd or a CD/DVD.

--EDIT
Otherwise, you can look towards mirroring the disk if it is supported.

VGCFGRESTORE(8) 					      System Manager's Manual						   VGCFGRESTORE(8)

NAME
vgcfgrestore - restore volume group descriptor area SYNOPSIS
vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName DESCRIPTION
vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and archive files of VolumeGroupName. OPTIONS
-l | --list -- List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore Vol- umeGroupName. -f | --file filename -- Name of LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfg- backup. See lvm for common options. REPLACING PHYSICAL VOLUMES
vgdisplay --partial --verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to restore the volume group's metadata. SEE ALSO
