> Since the backup did finish successfully couple of times, could it still be the connectivity issue which could be causing the backups to fail from other secondaries ?

Yes, connectivity issues may cause failed backups.

 

> Will the process block any write operations when the pbm backup is running ?

The backup doesn't block any writes. Just keep in mind it may influence write performance if running on the primary.

I tried running the backup against the primary and backup finished successfully.

Will the process block any write operations when the pbm backup is running ?

Done
