Theoretically speaking, I believe the greater danger (than deleting data) is the random alteration of data. For instance, if I discovered that I was missing data for 100 people, I could restore a backup copy to determine the missing records and then copy the missing individuals back into a database.
However, something that randomly changed a field in random records would be more difficult to recover. How would I know what data was changed correctly by a user vs. a 'bad script'.

vgcfgrestore
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.
