Last six months I did some simple bakup tests with Duplicati and was satisfied.
However recently I decided to use Duplicati on some file servers.
My objective was to backup some user shares and a general share several time during the day.
These shares do not change much, but we store our invoices and bank statements in these folders, so if we were e.g. hit by ransomware, the recent the backup the better.
Our company (multiple stores with own servers) are open from 8:00 - 18:00 from monday thru saturday.
I would prefere to backup the data every 2 hour or even every 1 hour, but alas if I choose that with Duplicati, it will keep backing up outside the working our of 8:00 - 18:00.
So as a compromise I backup every 4 hours starting at 02:00. This ensures that I have 3 backups (10:00, 14:00 and 18:00) between 8:00 - 18:00, and 3 backups I do not need at 02:00, 06:00 and 22:00.
Googling I found some I found some backup schedulers from other software.
With the shedulers below, you could choose the days to backup and add when wihin these days the backup should run.
In my case I could select mon, thu, wed, thu, fri and sat and e.g. backup at: 10:00, 12:00, 14:00, 16:00, 18:00 and 20:00.
Even better would be if one could shedule diffirent times for every day, but that would be to much of a stretch for this request
