Dear All, I have two questions regarding 1) cronjob and 2) time stamp I would like to know, How to setup cronjob to autobackup of database sql daily ?(before we close the library) Till now, I have enabled Cronjob with localhost:~# cd /usr/share/koha/bin/cronjobs localhost:~# crontab -u root crontab.example /usr/share/koha/bin/cronjobs shows - crontab.example and it has all the required instructions for the cron. I wanted to autobackup of koha db (example: at 5:15 pm daily before library closes) I tried with, following steps. 1. added in crontab -e #ADDED BY SATISH FOR DAILY BACKUP AT 5.15 PM DAILY 15 17 * * * mysqldump -uroot -pmysqlrootpassword dbname | gzip -9 > /home/satish/Dropbox/dbname.sql.gz When I check the dbsize, it is "zero". Therefore, It is not working! 2. by default Koha has /etc/cron.daily koha-run-backups --days 2 --output /var/spool/koha But, It backups when system boots every morning. how to schedule the time for the same? And Koha-run-backups has all the sql and config files backup. But I wanted have only complete db (sql). And also, our library works from 9:30 am to 5.30 pm on week days and 9:30-1:30 pm on every Saturday. (Desktop machine) as server, will be shutdown in the evening everyday until library receives a dedicated server machine. Currently, after setting up- Postfix mail agent, overdue message, advance due notice, check in, check out , new registration notice all are working fine,. but I wanted to setup timings as per the open and closing hours. The checkout Message includes (Notices Section): example Due Date: 20/09/2016 23:59 How to change the Due Date time from 23:59 to 5.30 pm or 17:30 ? My Koha Details are: Version -16.5.01 (upgraded from 3.16.00) OS: Ubuntu - 14.04 server edition (upgraded from 12.04) Install method - Packages Kindly share your best practices? with thanks Satish MV Librarian Govt.
