Possible issues with only cron chedules ?

Hi, I'm a new user of BBS, trying to replace a Synology Active Backup for Business system that I want to get rid of (because of the requirement to only run on specific distributions/kernels)
Let's imagine a client is intermittently up, like a desktop computer that is switched on to game/code/whatever for an hour or two a day.
If the backup schedule is always (by coincidence) run when the client is down/unavailable, the backup will never actually be run. Data that is supposed to be backed up will not be.
The situation can be detected, and the backup manually run, or the schedule changed to accomodate when the client is usually up, sure, but the point of automation is not to have to do it manually ^^
In previous backup software I was doing a backup every hour to ensure that it's run anytime the computer was up and joinable. It's a bit of an overkill, I think, this is not a disaster in space usage only because of the deduplication,
I actually only need a backup that is roughly ~daily
The agents are contacting BBS when up, the way they are polling, it should be possible to have a schedule is "run every day", not necessarily at a fixed time of day, or, like, "run when at least 12h have passed since last successful backup"

If I understand correctly you would like to schedule a daily backup to happen when the machine comes online ?

IMO that's an excellent idea , i would use that too

If there is a missed schedule, it should backup as soon as the agent comes online. I have a PC that is usually off. It's been off for 4 days you can see it's sitting in the queue, waiting:

Now I will turn on the PC and it immediately started backing it up.

Interesting ! I'll put that to the test on my side as well, if the cron schedule is for 'putting the job in queue and do it ASAP when the client is online', then that would work and avoid what I thought (which did happen when I used other backup systems :-) )

Yeah, if there's a missed schedule, it will backup when it comes offline. This was done because laptops are often not online on a schedule.

I get loads of these for laptop and mobile users and there is no way I can see to stop them.

at least one for every time a backup schedule is missed , its getting really distracting
