-Cloud File and Office 365 Exchange Online ​agentless backup jobs are supported since AhsayCBS ​version 7.9.0.0.+ 
 +<font color=red>​Important:​ 
 +<​br>​ 
 +To ensure ​agentless backup jobs (both manual triggered and scheduled job) do not consume all available memory of the AhsayCBS ​server, the default maximum number of manual and scheduled agentless backup jobs is limited to 2 (each agentless backup job requires an average of 170 MB of Java heap memory, for agentless backup sets that contain a lot of files / folder, the memory requirement will increase in proportion).

-To ensure agentless backup jobs do not consume all available memory of the AhsayCBS server, the maximum ​number of scheduled ​concurrent agentless ​backup jobs is limited ​to 2 by default (each agentless ​backup job requires an average of 170 MB of Java heap memoryfor agentless backup ​sets that contain a lot of files / folder, the memory requirement will increase in proportion).+If the number of scheduled backup jobs exceed the maximum concurrent setting, then the backup status of the job to be started, will be set to pending, AhsayCBS will attempt to retry and start the pending ​backup job(s) every minuteuntil the job can be successfully started. 
 +<​br>​ 
 +<​br>​ 
 +On the other hand, if you try to start an agentless backup ​job via the AhsayCBS web console when there are already 2 concurrent jobs running, the following error message would be displayed:​

-  <​br/>​ +
-For example, if the current maximum Java heap size setting is 2048 MB and you wish schedule 20 concurrent ​agentless backup ​jobs, then it is require that the server has roughly 3400 MB (20 jobs x 170 MBof additional ​Java heap memory ​available. To accomplish ​that, you will need to increase ​the maximum Java heap size to around 5500 MB (2048 MB + 3400 MB).+
   <br/>   <br/>
   <br/>   <br/>
 In addition to the extra Java memory usage, agentless backup jobs will also require extra CPU resources from AhsayCBS server due to the compression and encryption process during a backup job. In addition to the extra Java memory usage, agentless backup jobs will also require extra CPU resources from AhsayCBS server due to the compression and encryption process during a backup job.
