Thanx for the response, appreciate it
As to media, plan is to put it on disk, with some sort of raid(1, 5, 6)
to ensure safety/integrity, that is where the files are right now
as to the amount of data, it is not that huge, weekly full backups is
around 50 GB, and it lends it self well to compression, and data does
not change that much so incre. backups should be small, my concern is
mainly the database(using postgresql) and whether Bacula can handle
such retention times of say 3560+ days
I have seen reten times of one year but that is about it, if anyone
have experience of handling longer retention times and care to share
their experiences or config files for the jobs, I would be grateful
Hello Mehrdad,
The documentation says nothing about limit regarding retention.
At least I didn't notice such limit.
Retention is specified as a time data type.
For the time data type, the documentation on the page 217 states:
time
A time or duration specified in seconds. The time is stored internally
as a 64 bit integer
value, but it is specified in two parts: a number part and a modifier
part. The number
can be an integer or a floating point number. If it is entered in
floating point notation, it
will be rounded to the nearest integer. The modifier is mandatory and
follows the number
part, either with or without intervening spaces.
This is the relevant document for the version 15.0.x:
https://www.bacula.org/15.0.x-manuals/en/main/main.pdf
However, longer the retention, more data will be kept in the Bacula
catalog.
If that poses a problem, a solution would be to prune the data from the
catalog and store the volumes (preferably together with the bootstrap
files) and using bscan tool to load the data on the volume back into the
catalog if needed.
It would be a good idea to read this as well:
