backuplogs

NAME

backuplogs.<DDMMMYY> - Format of a Coda backup log file

DESCRIPTION

A backuplog is created each day with day, month and year appended to the name "backuplogs". The file backuplogs contains the following information collected by the backup and BSD dump programs:

the cloning process of each replica that makes up a Volume

the dump of each replica to local tape

Attempts to retry failed operations such as unable to contact a server

Successfully volumes (incrementals are marked, otherwise full backups are assumed

Lists any volumes that failed to be backed up

Lists any partially backup volumes (e.g if a replica was missed)

BSD Dump statistics

the disk image file names dumped to tape

This file may be used to identify successful, partially successful, partially failed, or complete failures of a backup to occur. It is also used to identify the replica file names that make up a Volume to used by merge(8) to restore a replica. Also note that the BSD restore command is used to retrieve files from a tape listed in the backuplogs.<date> file. Restore should be done via restore(1) command provided by the BSD-DUMP facility. The the most recent incremental(s) are then merged with the most recent full backup of a volume.
