Offline backups
To perform an offline backup of a database, use operating system
commands to copy the database directory. You must shut down the database prior
to performing an offline backup.
For example, on Windows systems, the following operating system command
backs up a (closed) database that is named sample and that is located in d:\mydatabases by
copying it to the directory c:\mybackups\2005-06-01:
xcopy d:\mydatabases\sample c:\mybackups\2005-06-01\sample /s /i
If you are not using Windows, substitute the appropriate operating
system command for copying a directory and all contents to a new location.
Note: On Windows systems, do not attempt to update a database while it is being
backed up in this way. Attempting to update a database during an offline
backup will generate a java.io.IOException. Using online backups prevents
this from occurring.
For large systems, shutting down the database might not be convenient.
To back up a database without having to shut it down, you can use an online backup.
