------------------------------
> Improve logging of exceptions that happen during execution of backup

> While backup is executed on the servers and fails due to exception e.g.
> "IOException: Not enough space left on device" then this exception (feedback)
> is not propagated to the user of DistributedSystemMXBean.backupAllMembers
> API. It will only get list of members and disk-stores for which backup is
> successfully executed. But it will not have indication what caused backup to
> fail for some members since Exception is not logged on server when using log
> level less than debug (config, warn, ...). It would be good to have at least
> have better logging for following cases:
> 1. Disk where oplogs are saved is to small for new oplog created by Geode
> backup procedure. This step is executed in Geode backup phase
> startDiskStoreBackup . If there is no enough space left on device, Geode will
> log that exception in DEBUG (see below). It would be good to have this logged
> in info or warning log level.
> 2. There is no enough space on disk where oplogs are copied for backup (this
> doesn't need to be the same disk as mentioned before, and it is not same disk
> for our case). This step in Geode is called completeBackup, and it doesn't
> log even debug log if problem appears, but disk stores are reported as
> offline (DiskBackupStatus.getOfflineDiskStores()). It would be good to have
> this exception logged in info or warning log level.
> Exception logged only in debug level:
> java.io.IOException: Not enough space left on device
