Hello ,
Im stuck trying to exclude directories (not whole filesystems) from one of our backup media servers, I need that in order to get the iso file smaller, so I put into my local.conf :
BACKUP_PROG_EXCLUDE=( ${BACKUP_PROG_EXCLUDE[@]} '/usr/openv/netbackup/client/*' '/usr/openv/pack/*' '/usr/openv/logs/*' )

But when I launch rear I get that output :

2019-03-05 12:20:24 Files being excluded: dev/shm dev/oracleasm dev/.udev dev/shm/* /etc/pki/tls/private /etc/pki/CA/private /etc/pki/nssdb/key*.db /us /openv/netbackup/bin/xbp

So it seems like he is not excluding the sub-folders

Not sure if its related but /usr/openv is a filesystem mount

root@DELZP042-PRO:/root# df -Ph /usr/openv/ 
Filesystem               Size  Used Avail Use% Mounted on 
/dev/mapper/vg00-lv_nbu   20G  6.9G   12G  37% /usr/openv

My local.conf :

OUTPUT=ISO 
BACKUP=NBU
COPY_AS_IS_NBU=( /usr/openv  /opt/VRTSpbx   /etc/vx   /etc/init.d/vxpbx_exchanged  )                                                                                                                                                                                                                                                                                                                                                                                                                                          ONLY_INCLUDE_VG=("vg00")

I do not use NBU (Symantec/Veritas NetBackup)
because I do not have any kind of proprietary software
like third-party backup tools but I assume
BACKUP_PROG_EXCLUDE is not supported for BACKUP=NBU
because this are the only ReaR scripts that use BACKUP_PROG_EXCLUDE

# find usr/share/rear -name '*.sh' | xargs grep -l "BACKUP_PROG_EXCLUDE"
usr/share/rear/layout/save/default/320_autoexclude.sh
usr/share/rear/backup/RSYNC/default/400_create_include_exclude_files.sh
usr/share/rear/backup/TSM/default/400_create_include_exclude_files.sh
usr/share/rear/backup/NETFS/default/400_create_include_exclude_files.sh
usr/share/rear/backup/YUM/default/400_create_include_exclude_files.sh
usr/share/rear/backup/BORG/default/400_create_include_exclude_files.sh

See the BACKUP SOFTWARE INTEGRATION section in man rear
https://github.com/rear/rear/blob/master/doc/rear.8.adoc

See also usr/share/rear/conf/default.conf (excerpts)

# Internal BACKUP stuff
##
# These settings apply to all cases of internal Relax-and-Recover backup
...
# BACKUP_PROG_EXCLUDE is an array of strings that get written into a backup-exclude.txt file
# that is used e.g. in 'tar -X backup-exclude.txt' to get things excluded from the backup.

but you do not use a ReaR internal backup method but
the third-party BACKUP=NBU method, see also the section about
"Relax-and-Recover versus backup and restore" in
https://en.opensuse.org/SDB:Disaster_Recovery

Hello, thanks for the reply, I realized here I have a defined variables with the paths :

root@DELZP042-PRO:/root# grep -Ri logs /usr/share/rear/* \| grep NBU 
/usr/share/rear/conf/default.conf:COPY_AS_IS_EXCLUDE_NBU=( "/usr/openv/netbackup/logs/*" "/usr/openv/netbackup/bin/bpjava*" "/usr/openv/netbackup/bin/xbp" '/usr/openv/netbackup/client/*' '/usr/openv/pack/*'  )
/usr/share/rear/conf/examples/RHEL6-NETFS-of-NBU-master-example.conf:BACKUP_PROG_EXCLUDE=( "${BACKUP_PROG_EXCLUDE[@]}" '/usr/openv/tmp/*' '/nbu/logs/openv/logs/nbdisco/*' '/nbu/logs/openv/logs/nbsvcmon/*' '/nbu/lo gs/openv/logs/nbrmms/*' '/nbu/logs/openv/logs/nbsl/*' ) 

So I have edited this file the /usr/share/rear/conf/default.conf and I placed the directories I wanted to exclude, now it seems to be working .

May I ask if I can append those directories from my os.conf or my local.conf in some way since I understand the file /usr/share/rear/conf/default.conf is not supposed to be modified

[gdha]

If you add these variables in the /etc/rear/local.conf file then they will over-rule the ones defined in the default.conf file

[flechoide]

I realize that syntax is bash ?? Its an asociative array ?? If I do in my local.conf

COPY_AS_IS_EXCLUDE_NBU=( ${COPY_AS_IS_EXCLUDE_NBU[@]}  "/usr/openv/netbackup/logs/*" "/usr/openv/netbackup/bin/bpjava*" "/usr/openv/netbackup/bin/xbp" '/usr/openv/netbackup/client/*' '/usr/openv/pack/*'  )

I understand it will work as expected

@flechoide
basically all in ReaR is bash, also config files
are sourced and executed as bash scipts.

Normally ReaR does not use associative arrays - only indexed arrays.
But I know nothing about how NBU stuff is implemented in ReaR.

In general COPY_AS_IS variables mean totally different things
than backup related stuff - but I know nothing about NBU and
how NBU stuff is implemented in ReaR.

[flechoide]

Ok, I understand, I thank you all for the help, finally I was able to implement the backup and it worked as expected with the COPY_AS_IS_EXCLUDE_NBU variable into the local.conf file from /etc/rear .

Please the case can be closed
