First post, weee.

 

Any idea why I'm getting this error.  The folder does exist.

 

ERROR: backup /mnt/user/Private/ localhost/ - Source directory \
"/mnt/user/Private/" doesn't exist

Because you don't understand how volume bind mounts work in docker?

 

Always post the docker run command if you want help.

I have edited rsnapshot.conf and crontabs/root in the appdata directory as follows and then restarted the docker, but the cron does not seem to get started. I do not see any snapshots being created so far. Is there anything else that needs to be done?

 

# do daily/weekly/monthly maintenance
# min   hour    day     month   weekday command
*/15    *       *       *       *       run-parts /etc/periodic/15min
0       *       *       *       *       run-parts /etc/periodic/hourly
0       2       *       *       *       run-parts /etc/periodic/daily
0       3       *       *       6       run-parts /etc/periodic/weekly
0       5       1       *       *       run-parts /etc/periodic/monthly

# rsnapshot examples
0       */2     *       *       *       rsnapshot alpha
30      4       *       *       *       rsnapshot beta
30      23      *       *       0       rsnapshot gamma

The configuration should trigger alpha backups every 2h, beta backups daily at 4:30am and gamma backups weekly on Sunday evening (23:30).

It was an error in the config file. To check syntax I suggest running 

rsnapshot configtest

inside the docker container, as stated on the GitHub page for rsnapshot https://github.com/rsnapshot/rsnapshot/blob/master/README.md#configuration

This docker has a little bug. /root/.ssh/ dir schould be mounted and persistent, as after container reinstall known_hosts and private keys are lost. As workaround I am using:

ssh -i /config/id_rsa -o UserKnownHostsFile=/config/known_hosts -p 222 root@your.server.ip

 

and my settings in rsnaphost.conf:

 

ssh_args        -i /config/id_rsa -o UserKnownHostsFile=/config/known_hosts -p 222
rsync_short_args        -az

# My mysql dump on my debian machine:
backup_exec     ssh -i /config/id_rsa -o UserKnownHostsFile=/config/known_hosts -p 222 root@your.server.ip "mysqldump --defaults-file=/etc/mysql/debian.cnf --all-databases| bzip2 > /root/mysqldump.sql.bz2"
# Then backup whole /root folder
backup  root@your.server.ip:/root        your.server.ip/
# and etc www vmain folders - it is ISPCONFIG machine
backup  root@your.server.ip:/etc/        your.server.ip/
backup  root@your.server.ip:/var/www/clients     your.server.ip/
backup  root@your.server.ip:/var/vmail   your.server.ip/

 

 

Of course to install private key ssh login option do:

# Only once to generate key
ssh-keygen
# do this for each server where you want to install your private key
ssh-copy-id -i /config/id_rsa -p 222 root@your.server.ip

 

 

To make this post complete:

• it is required to modify crontabs:

root@nas:/mnt/user/appdata/rsnapshot-backup/crontabs# cat root
# do daily/weekly/monthly maintenance
# min   hour    day     month   weekday command
*/15    *       *       *       *       run-parts /etc/periodic/15min
0       *       *       *       *       run-parts /etc/periodic/hourly
0       2       *       *       *       run-parts /etc/periodic/daily
0       3       *       *       6       run-parts /etc/periodic/weekly
0       5       1       *       *       run-parts /etc/periodic/monthly

# rsnapshot examples
0      0     *       *       *       rsnapshot daily
0      1     *       *       1       rsnapshot weekly
0      2     1       *       *       rsnapshot monthly

 

• and in rsnapshot.conf:

#########################################
#     BACKUP LEVELS / INTERVALS         #
# Must be unique and in ascending order #
# e.g. alpha, beta, gamma, etc.         #
#########################################

retain  daily   7
retain  weekly  4
retain  monthly 3
