backup.pl - gzip not working as expected!?

Hi,

I wondered for some time - since Friday 21.5.2021 ( ;-) ) - that the IPF files of the ISO backups turned out much larger than before.

Today I tested: when I make a backup *without* logs, the resulting IPF is about *26MB* in size.

The same file is about *108MB* in size when I make an *ISO backup*.

So I ran ' /var/ipfire/backup/bin/backup.pl iso' from console and watched the output.

After some time, 'gzip' told me:

... gzip: /var/ipfire/backup/2021-12-25-20:34.ipf already has .ipf suffix -- unchanged ...

For results, please see attached screenshot (and yes: I use tables... ;-) ).

The first IPF was created using 'Generate ISO', the second using 'Exclude logfiles'.

Can anyone confirm?

Best, Matthias
