Hello,
I've got two questions on .bsr files. First, when a job runs and a
.bsr file is created by the job if one is already in the location
specified in the job definition is it overwritten or appended to?
That is, as far as I know, much more complicated.
Bootstrap files are always completely overwriten when a full backup
happens. An incremental backup only appends to the bootstrap file.
Differential backups should be the most interesting case: As far as I
understand, in this case all data from previous differential or
incremental backups should be purged from the bootstrap file, the last
full backup would be kept, and the data for the new differential backup
would be appended. (Technically, I suspect that re-creating the whole
file whenever it's written is the easier solution, but what I described
*should* be what you see when you observe the files contents.)
All as far as I know, recalling some of Kern's mails, and without
actually verifying, either in the code or the manual.
And
second, if they're overwritten is it possible to have a filename like
systemname-formatteddate.bsr?
No, not as far as I know. Given the above, it would not be very useful
to store a bootstrap file for an incremental backup only.
It would be nice, though, to have the usual variable expansion working
in the bootstrap file definition, so you only define it once like %c.bsr
(assuming %c would expand to the client name) in the default settings.
Thanks.
Always a pleasure :-)
By the way - why would you want bootstrap files for each job,
independant of each other? I understand that these files are the
quickest way to recover in a real desaster situation, i.e. without
catalog. But in that case you want full restores, I'd say...
