ACE Management Server Administrator's Manual
Database Backup
If you are using an external database, use a backup and recovery strategy that is
appropriate for your database system. Back up your ACE Management Server database
on a regular basis to ensure that the database can be recovered promptly if needed.
If you are using the embedded database, you can use standard file‐backup tools, such
as ntbackup or dd. The data is stored in one of the following locations:
Windows – C:\Program Files\VMware\VMware ACE Management
Server\db\acesc.bin.
Linux – /var/lib/vmware/acesc/db/acesc.bin
If you are using the embedded database in a production environment, stop the server,
copy the file to a different location for the backup, and restart the server. SQLite is file
based, so the database file might be modified by the ACE Management Server process
at the same time that it is being copied for backup. An inconsistent database snapshot
might be produced. This problem is unlikely to occur because the file is usually not
large and is copied quickly.
Other alternatives for backing up an open database, as recommended by members of
an SQLite community, are the following:
Use the sqlite3 command‐line tool to log in to the SQLite database. Use the .dump
command, store the result in a separate file, and back up that result file. An SQL
script recreates the database.
Use the Shadow Volume Copy mechanism on Windows systems or LVM volume
snapshots on Linux (and the crash‐restore feature of SQLite) to back up the
complete database directory, including journal files if they are present. On a
Windows XP SP1 or later operating system, use ntbackup on the database
directory.
Use the sqlite3 command‐line tool to log in to the SQLite database. Use the
BEGIN EXCLUSIVE command, copy the database file, and then use the COMMIT
command.
For information to help you use your company's own management or reporting tools
or automated scripts with the data in the VRM database, see "Appendix: Database
Schema and Audit Event Log Data" on page 75.
