The line in amzfs-sendrecv which is responsible for this is:
amzfs-sendrecv:
225 # destroy all snapshot of this level and higher
226 $self->zfs_purge_snapshot($level, 9);
Is there a way to check if the snapshot that would be deleted is still
on any tape ? I had a look into
lib/perl5/site_perl/5.14.1/Amanda/Application/Zfs.pm but couldn't find
any function that help with that. BTW this is on amanda 3.2.2. I tried
upgrading but then local auth stopped working. Have there been changes
in said files in-between?
thanks,
Leon
