backupmanager.sh

example jobs

each job file needs to be located in one of the job folders (01_daily-jobs, 02_weekly-jobs, 03_monthly-jobs)
each job file needs to end in .job
the following variables are passed on from the main script
- BACKUPDIR -> path where the backupfile should be placed (e.g. /srv/backup-data/01_daily/2016-05-23)
- FILEDESC -> datecode to be used in the filename
- TEMPDIR -> can optionally be used for temp files

single folder

weak compression

ARCHIV="$BACKUPDIR/${FILEDESC}_server_srv_www.tar.gz"
tar -c /srv/www | pigz --best > $ARCHIV

strong compression

ARCHIV="$BACKUPDIR/${FILEDESC}_server_srv_www.tar.7z"
tar -c /srv/www | 7z a -m0=lzma2 -mx9 -si $ARCHIV

multiple files/folders

CURDIR=$(pwd)
ARCHIV="$BACKUPDIR/${FILEDESC}_hostname_srv.tar.gz
INCLUDE="--files-from=$CURDIR/backup_srv.include"
EXCLUDE="--exclude-from=$CURDIR/backup_srv.exclude"
tar $EXCLUDE -c $INCLUDE | pigz --best > $ARCHIV

remove old backups, keep new backups

KEEP="4"
cd $BACKUPDIR
cd ..
ls -r | sed -e 1,${KEEP}d | xargs rm -r

rsync backup files to other ssh server

rsync -avz -e ssh $BACKUPDIR username@hostnameoftarget:/srv/backup-data/targetfolder

rsync backup from local to samba share

/root/.smb_cred

username=testuser
password=password1234

70_mountcifs.job:

mount -t cifs -o credentials=/root/.smb_cred //sambaserver/sambashare /mnt/localmountpoint

71_remotesync.job:

rsync -avz -P /srv/somelocalfolder /mnt/localmountpoint/destinationfolder
