If you have a non-vss aware application (e.g. +SQL Anywhere or probably MySQL), a shadow copy is still generated +and the open files can be backed up, but there is no guarantee +that the file is consistent. + +Bacula produces a message from each of the registered writer programs +when it is doing a VSS backup so you know which ones are correctly backed +up. + +Bacula supports VSS on both Windows 2003 and Windows XP. +Technically Bacula creates a shadow copy as soon as the backup process +starts.

Begin by editing the {\bf pg_hba.conf} file, and +just prior the the existing ``local'' and ``host'' lines, add the line: + +\footnotesize +\begin{verbatim} + local bacula bacula md5 +\end{verbatim} +\normalsize + +and restart the Postgres database server (frequently, this can be done +using "/etc/init.d/postgresql restart") to put this new authentication +rule into effect. + +Next, become the Postgres administrator, postgres, either by logging +on as the postgres user, or by using su to become root and then using +su - postgres to become postgres. Add a password to the bacula +database for the bacula user using: + +\footnotesize +\begin{verbatim} + \$ psql bacula + bacula=# alter user bacula with password 'secret'; + ALTER USER + bacula=# \\q +\end{verbatim} +\normalsize + +Next, you'll have to add this password to two locations in the +bacula-dir.conf file: once to the Catalog resource and once to the +RunBeforeJob entry in the BackupCatalog Job resource. With the +password in place, these two lines should look something like: + +\footnotesize +\begin{verbatim} + dbname = bacula; user = bacula; password = "secret" + ... and ... + RunBeforeJob = "/etc/make_catalog_backup bacula bacula secret" +\end{verbatim} +\normalsize + +Naturally, you should choose your own significantly more random +password, and ensure that the bacula-dir.conf file containing this +password is readable only by the root. + +Even with the files containing the database password properly +restricted, there is still a security problem with this approach: on +some platforms, the environment variable that is used to supply the +password to Postgres is unavoidable made available to all users of the +local system. To eliminate this problem, the Postgres team have +deprecated the use of the environment variable password-passing +mechanism and recommend the use of a .pgpass file instead. To use +this mechanism, create a file named .pgpass containing the single +line: + +\footnotesize +\begin{verbatim} + localhost:5432:bacula:bacula:secret +\end{verbatim} +\normalsize + +This file should be copied into the home directory of all accounts +that will need to gain access to the database: typically, root, +bacula, and any users who will make use of any of the console +programs. The files must then have the owner and group set to match +the user (so root:root for the copy in ~root, and so on), and the mode +set to 600, limiting access to the owner of the file. \subsection*{Re-initializing the Catalog Database} \index[general]{Database!Re-initializing the Catalog } diff --git a/docs/manual/tapetesting.tex b/docs/manual/tapetesting.tex index b2ee2e83..875ace8f 100644 --- a/docs/manual/tapetesting.tex +++ b/docs/manual/tapetesting.tex @@ -1078,7 +1078,7 @@ number of sequential reads as it had written. \index[general]{Modes!Details} \index[general]{Details of Tape Modes} \addcontentsline{toc}{subsection}{Details of Tape Modes} -Rudolf Cejkar has provided the following information concerning +Rudolf Cejka has provided the following information concerning certain tape modes and MTEOM. \begin{description} diff --git a/docs/manual/tls.tex b/docs/manual/tls.tex index 237a165f..4174aa3b 100644 --- a/docs/manual/tls.tex +++ b/docs/manual/tls.tex @@ -123,6 +123,10 @@ valid for 10 years can be made with the following: The above script will ask you a number of questions.
