MySQL Enterprise Backup User's Guide (Version 3.11.1)
Each backup directory includes some files in the
meta
subdirectory that detail how the backup
was produced, and what files it contains. The files containing
this information are known collectively as the
manifest.
mysqlbackup produces these files for use by database management tools; it does not consult or modify the manifest files after creating them. Management tools can use the manifest during diagnosis and troubleshooting procedures, for example where the original MySQL instance has been lost entirely and the recovery process is more substantial than copying files back to a working MySQL server.
The files in the manifest include:
backup_create.xml
: information about the
backup operation.
backup_content.xml
: information about the
files in the backup. This information is only complete and
consistent when the backup operation succeeds. The contents of
this file might be expanded in the future. A management tool
might use this information to confirm which tables are part of
a full backup, or a partial backup performed with the
--databases
option. (The
information is not present for partial backups taken with the
--include
,
--incremental
,
--incremental-with-redo-log-only
,
--only-innodb
, or
--only-innodb-with-frm
options.) A
management tool might compare the checksum recorded in the
manifest for a single-file backup against the checksum for the
file after the single-file backup is unpacked. The file also
contains details of all the plugins defined on the backed-up
server, by which users should make sure the same plugins are
defined in the same manner on the target server for
restoration.
image_files.xml
: information about the
files in a single-file backup. (Only produced for backups
taken with the backup-to-image
and
backup-dir-to-image
options.) A
management tool might use the paths recorded in this file to
plan or automate the unpacking of a single-file backup using
the image-to-backup-dir
or
extract
options, or to remap the paths of
extracted files with the
--src-entry
and
--dst-entry
options.
