<H3>Summary:</H3>
|
|
The <B>crashbackups</B> procedure enables or disables the
|
|
periodic saving of crash recovery backup files.
|
|
<B>crashbackups</B> or <B>crashbackups start</B> sets the
|
|
timer for the first periodic save. After the timer times
|
|
out, backup file is generated and written in the system
|
|
temporary directory, and the timer is reset. By default,
|
|
the backup interval is 10 minutes (600000 msec). The
|
|
interval can be changed by setting the value of Tcl variable
|
|
<B>$Opts(backupinterval)</B> to the interval value in msec. <BR><BR>
|
|
|
|
<B>crashbackups stop</B> removes the timer callback and thus
|
|
prevents further writing of backup files. Note that if
|
|
crash recovery is stopped or started multiple times during
|
|
a session, the same filename is used to save the data.

<H3>Implementation Notes:</H3>
|
|
<BLOCKQUOTE>
|
|
<B>crashbackups</B> is implemented as a Tcl procedure in the
|
|
"tools.tcl" script file. It calls the magic command
|
|
"<B>crash save</B>".
