in the /etc/lvm/backup file and the metadata archives are stored in the /etc/lvm/archive
file. How long 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.
Note that a metadata backup does not back up the user and system data contained in the logical
volumes.
You can manually back up the metadata to the /etc/lvm/backup file with the vgcfgbackup
command. You can restore metadata with the vgcfgrestore command. The vgcfgbackup and
vgcfgrestore commands are described in Section 4.3.12, “Backing Up Volume Group Metadata”.
3.5. Logging
All message output passes through a logging module with independent choices of logging levels for:
• standard output/error
• syslog
• log file
• external log function
The logging levels are set in the /etc/lvm/lvm.conf file, which is described in Appendix B, The
LVM Configuration Files.
