For QNAP NAS devices, we have dedicated AhsayOBM agents for directly installation on the NAS devices to backup files with the NAS. You can also map the NAS device as a network share and back it up with AhsayOBM / AhsayACB running on another machine.

login as: admin
admin@'s password:
[~] # ps -ef|grep java
 3562 admin    640772 S /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/jvm/bin/java -Xrs -Xms64m -Xmx1024m -Dsun.nio.PageAlignDirectMemory=true -Djava.library.path= . -cp .:./cb.jar WuiService /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm /share/CACH EDEV1_DATA/.qpkg/AhsayOBM/.obm --port=32168
11017 admin 956 S grep java
20327 admin 157000 S /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/jvm/bin/java -Xms64m -Xmx256m -Dsun.nio.PageAlignDirectMemory=true -Djava.library.path=. -cp .:./cbs.jar cbs /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm

Scheduler service is running as shown above (20327 admin…).

Manaully Stop Scheduler Service

To manually stop the scheduler service, use the touch /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/ipc/Scheduler/stop script and use the ps command.

[~] # touch /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/ipc/Scheduler/stop
[~] # ps -ef|grep java
 3562 admin 640772 S   /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/jvm/bin/java -Xrs -Xms64m -Xmx1024m -Dsun.nio.PageAlignDirectMemory=true -Djava.library.path=                        . -cp .:./cb.jar WuiService /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/.obm --port=32168
12542 admin 1000 S grep java

Manaully Start Scheduler Service

To manually start the scheduler service, use the /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/bin/ script and use the ps command again.

[~] # /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/bin/
[~] # ps -ef|grep java
 3562 admin 640772 S /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm/jvm/bin/java -Xrs -Xms64m -Xmx1024m -Dsun.nio.PageAlignDirectMemory=true -Djava.library.path=. -cp .:./cb.jar WuiService /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/obm /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/.obm --port=32168

During installation, the following symlinks to the scheduler startup script /share/CACHEDEV1_DATA/.qpkg/AhsayOBM/ will be created that allows the AhsayOBM Scheduler Service to start automatically each time the machine is rebooted or restarted.

To verify if the symlinks have been created correctly, use the ls command. You will see the symlink.
