rdiff-backup-statistics - summarize rdiff-backup statistics files SYNOPSIS
rdiff-backup-statistics [--begin-time time] [--end-time time] [--minimum-ratio ratio] [--null-separator] [--quiet] repository DESCRIPTION
rdiff-backup-statistics reads the matching statistics files in a backup repository made by rdiff-backup and prints some summary statistics to the screen. It does not alter the repository in any way. The required argument is the pathname of the root of an rdiff-backup repository. For instance, if you ran "rdiff-backup in out", you could later run "rdiff-backup-statistics out". The output has two parts. The first is simply an average of the all matching session_statistics files. The meaning of these fields is explained in the FAQ included in the package, and also at The second section lists some particularly significant files (including directories). These files are either contain a lot of data, take up increment space, or contain a lot of changed files. All the files that are above the minimum ratio (default 5%) will be listed. If a file or directory is listed, its contributions are subtracted from its parent. That is why the percentage listed after a directory can be larger than the percentage of its parent. Without this, the root directory would always be the largest, and the output would be boring. OPTIONS
--begin-time time Do not read statistics files older than time. By default, all statistics files will be read. time should be in the same format taken by --restore-as-of. (See TIME FORMATS in the rdiff-backup man page for details.) --end-time time Like --begin-time but exclude statistics files later than time. --minimum-ratio ratio Print all directories contributing more than the given ratio to the total. The default value is .05, or 5 percent. --null-separator Specify that the lines of the file_statistics file are separated by nulls (). The default is to assume that newlines separate. Use this switch if rdiff-backup was run with the --null-separator when making the given repository. --quiet Suppress printing of the "Processing statistics from session..." output lines. BUGS
When aggregating multiple statistics files, some directories above (but close to) the minimum ratio may not be displayed. For this reason, you may want to set the minimum-ratio lower than need. AUTHOR

vxconfigbackupd - disk group configuration backup daemon SYNOPSIS
vxconfigbackupd [-l] DESCRIPTION
The vxconfigbackupd daemon automatically backs up information about a disk group's new configuration whenever the configuration is changed. OPTIONS
-l Logs backup daemon activities to the file /etc/vx/cbr/bkdaemonLog. FILES
/sbin/init.d/vxvm-recover Startup file for vxconfigbackupd. /etc/vx/cbr/bk/dgname.dgid/dgid.dginfo Location of backup file for disk group information. /etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo Location of backup file for disk attributes. /etc/vx/cbr/bk/dgname.dgid/dgid.binconfig Location of backup file for binary configuration copy. /etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec Location of backup file for configuration records in vxprint -m format. NOTES
The vxconfigbackup command can be used to back up a disk group's configuration manually at any desired time. The disk group configuration backup and restore utilities do not save any data in the public region. This includes file system or other application data that is configured within VxVM objects. When a disk group is destroyed, its configuration backup information (including the backup directory) is also removed. The only exception to this behavior is when the disk group is in the precommit state of restoration. The backup directory should be large enough to accommodate copies of all the currently imported disk groups. The minimum recommended size of the backup directory is P * (N + 1) megabytes, where P is the private region in megabytes (by default, 32MB), and N is the number of disk groups. The additional P megabytes is required to hold a temporary copy of the disk group configuration when a disk group is imported or a configuration change is made. The default backup directory is /etc/vx/cbr/bk. The location of the backup directory can be configured by using the vxconfigbackup -l backup_directory_path command. SEE ALSO
