Backup is being submitted for only few streams

We have a policy with a client on which we have 21 file systems. It is supposed to submit 21 streams when a scheduled backup kicks in. However, we noticed that only 10 streams are being submitted following a previous failed scheduled backup. What could have gone wrong ??

I would suggest you check "max job per client" in the Master Server General Settings

Please show us policy config:
bppllist <policy-name> -U

as well as STU config:
bpstulist -label <stu-name> -U

Check master server Host  Properties -> Global Attributes -> Max jobs per client.
Please tell us what this setting is.

Show us backups done over the last 3 days for this client:
bpimagelist -client <client-name> -hoursago 72 -U

We should be able to pinpoint the problem with all of above info.

MPX in schedule:
Maximum MPX:     2

STU: 
Concurrent Jobs:      3

Seems 2 jobs will be activated simultaneously.
The rest will be queued.
Because you have Multiple Data streams enabled and your frequency is every one day (every 24 hours), each new stream will be evaluated separately, based on when last a successful backup for this stream was started. This becomes progressive worse every day - backups are no longer submitted when backup window opens - only 24 hours after the start of previous successful backups. 
We call this 'schedule creeping'.

Why the big difference in daily backup windows?
And exceptionally large open window on most days?

The current backup windows make it difficult to cater for 'schedule creeping' due to small amount of concurrent backups allowed.
You will be better off allowing more simultaneous streams in DSU and higher MPX in schedule with smaller backup window and smaller frequency. e.g. if backup window is 8 hours, make frequency every 9 hours.
This will ensure that next day's backup is attempted as close as possible to backup window start time .

Please see David Chapa's article about Frequency based schedules:
