1. Install duply and dependences (as root).
sudo apt-get install duplicity duply python-boto
2. Create backup profile (as root).
sudo duply bck_profile create
3. Edit profile /root/.duply/bck_profile/conf like as:
GPG_PW='___YOUR GENERATED PASSWORD____'
TARGET='s3://s3-endpoint-name.amazonaws.com/bucket-name/directory/for/backup/'
TARGET_USER='AWS_KEY_ID'
TARGET_PASS='AWS_SECRET_KEY'
SOURCE='/'
MAX_AGE=6M
#MAX_FULL_BACKUPS=1
#VERBOSITY=5
TEMP_DIR=/content
#DUPL_PARAMS="$DUPL_PARAMS --time-separator _ "
#DUPL_PARAMS="$DUPL_PARAMS --short-filenames "
MAX_FULLBKP_AGE=1W
DUPL_PARAMS="$DUPL_PARAMS --full-if-older-than $MAX_FULLBKP_AGE "
VOLSIZE=200
DUPL_PARAMS="$DUPL_PARAMS --volsize $VOLSIZE "
4. Edit /root/.duply/bck_profile/excludes to include the list of non wanted directories such as:
- /dev
- /home/*/.cache
- /home/*/.ccache
- /lost+found
- /media
- /mnt
- /proc
- /root/.cache
- /root/.ccache
- /run
- /selinux
- /sys
- /tmp
- /var/cache/*/*
- /var/log
- /var/run
- /var/tmp
5. Tun a full backup test:
sudo duply bck_profile backup
6. Configure crone for daily backup:
sudo crontab -e
and add:
0 2 * * * duply bck_profile backup
7. Some useful commands to operate your backup:
To get current list of present backups.
sudo duply status
To restore all files from last backup to /target_dir
sudo duply restore /target_dir
To restore directory etc from last backup to /target_dir
sudo duply fetch etc /target_dir
Note:
All backups early than MAX_FULLBKP_AGE=1W will be incremental, every MAX_FULLBKP_AGE=1W will create full backup.
