Backup Central

Hello,

I probably missed this in the documentation (though I did look for it). How does rsnapshot process backups for the hosts listed in the configuration file? In the order entered? Also, does it run one after another or does it try to run all backups simultaneously?

Thanks.

Yes; check man rsnapshot and look for "retain".

try to run all backups simultaneously?

This can also be inferred from the section on "retain". Basically, it
takes the snapshot you specify on the command line. So, if you have an
hourly retain target defined, then 'rsnapshot hourly' performs the hourly
backup. (This makes defining crontab entries fairly straightforward.)

You can always use the -t switch to show you what would be run without
actually running it.

Oh, boy, talk about misreading! Many apologies for seeing "retain"
instead of "hosts.

I don't think the order is documented, but it *currently* does them in
the order they're defined in the config file, one at a time.
