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 backu‐
plogs.<date> file. Restore should be done via restore(1) command pro‐
vided by the BSD-DUMP facility. The the most recent incremental(s) are
then merged with the most recent full backup of a volume.
