hi!
all servers to backup are linux servers.
server1 has 100 servers to backup: 487.31GB containing 17536889 files
and 4829 directories
server2 has 68 servers to backup: 740.42GB containing 8111272 files and
4369 directories
backupPC processes run as user "wwwrun" - this is the apache user -
because of the permissions making the configuration over the webinterface.
the archive request get startet over a cronjob and a small skript once a
week:
"sudo -u wwwrun /usr/local/BackupPC/bin/BackupPC_archiveStart
archive-tape xadmin $XALL_HOSTS"
where the variable XALL_HOSTS contain all hosts of the backupPC server.
some of the archives get completed and later it fails and don't continue
with the next archive.
logfile - error at the end:

exiting after signal ALRM
Archive failed: aborted by signal=ALRM
the strange thing is, that the duration shows ~1200 min on both
backupPC servers for the archive job, when it fails.
is there a limitation anywhere in the code?
I tested both: archiving with and without split and both fail
changing the splitsize value for a host is written into the config but
it does not get read, when the scripts
"/usr/local/BackupPC/bin/BackupPC_archiveStart" runs - there it is
hardcoded!
why? I changed this by my own.
