DESCRIPTION

Use the evms_metadata_backup utility to save a copy of all

the metadata that are used to build the segments (partitions),

regions, containers (groups), and volumes in the system. The

metadata are saved in a file named "evms-metadata-yyyy-mm-dd

hh.mm.ss", where "yyyy-mm-dd-hh.mm.ss" is the time of the backup.

OPTIONS

The following options can be used with

evms_metadata_backup:

-d, --debug-level debug_level

Specify the amount of information that should be

written to the log file. A numerical value between 0 and 9 can

be specified, where a larger number generates more logging infor

mation. The following text values are also allowed:

critical
serious
error
warning
default
details
entry_exit
debug
extra
everything

"Critical" generates the least information and "ev

erything" generates the most information. The default debug lev

el is "default" or "5."

-l, --log-file log_file_name

Specify the location of the log file. The default

value is /var/log/evms-engine.log.

-n, --node-name node_name

Specify the node in the cluster on which the backup

should be performed. The default value is the local node. If

EVMS is not running in a cluster, this option is ignored.

-q, --quiet

Display only error messages.

-v, --verbose

Display verbose status information about the

progress of the backup.

-h, -?, --help

Display a summary of the options available for

evms_metadata_backup.
