The option to create an incremental schedule is unavailable (grayed out) in the scheduling interface

Symptoms

If the incremental option is grayed out in the schedule, there are two possible causes.

---

Case1:
1) Existing backup tasks are already in place.

2) Incremental backups are limited to one volume per schedule. For instance, the "C drive" cannot be included in a multi-volume incremental schedule.

---

Case 2:
If there are no existing backup tasks:

– Tracking information has not been deleted.
– Incorrect tracking information is exists.
– Issue may occur by a change of the host name.

Reproduced in the following operation has been confirmed.

Steps to reproduce:

1) Create a base and incremental schedule.
2) Run the backup task several times.
3) Change the host name, and then reboot the system.
4) Delete an existing schedule.
5) Create a scheduled task that contains the same volume again.

Workaround

1) Open the installation path by Explorer.
e.g. C: Program Files (x86) ActiveImage Protector Server

2) Run the aipcontrol.exe

3) Enter the following command.

stoptracking <image path>

In a local disk path environment:
U:aip_backuptest@disk_all_d00_00002.aiv

stoptracking U:aip_backuptest@disk_all.aiv

In a network share path environment:
\bkserveraip_backuptest@disk_all_d00_00002.aiv

stoptracking \bkserveraip_backuptest@disk_all.aiv

To delete all of the tracking information, run the following command:

stoptracking *

Note:  After running the command “stoptracking”, the first time backup task becomes the Base backup.

4) re-create the schedule
