Instructions on how to troubleshoot and resolve issues with disk/partition backup failures
Backup of drives or partitions may fail due to a variety of reasons, but not all reasons are specific to this type of backup. Generally the problem can be treated as a partition backup failure only when you also tried to run a file backup
This article provides information on troubleshooting possible failures during Deduplication.
Deduplication is a complex process involving many operations and components and thus has a number of possible points of failure. In order to properly troubleshoot and resolve such issues, the first step is to find the exact point of failure. Once this clear, we have to collect the proper diagnostic information.

The Express Full Backup method allows creating full backups of Exchange information stores, storage groups, or databases in deduplicating vaults. With this method, Acronis software backs up only the changes that have occurred since the previous full backup. The data that has not changed is replaced with links to it in a newly created backup.

Collect information for investigation of Linux operating system lockups.
Operating system may hang under specific circumstances. To identify the exact cause, it is necessary to analyze Acronis System Report and a kernel dump.
Always make sure you have the latest build of the product (if it's possible).
Under specific circumstances, the software may crash. It is very important to report a crash instead of trying to workaround it. Normal workflow for a crash problem is the following:
While using the VSS backup option to back up complex applications, you may encounter issues with creating volume snapshot/shadow copy. This article provides instructions on how to troubleshoot and resolve such issues.
Product may hang under specific circumstances.
There are 2 types of hanging:
Usually when a software hangs its process uses either 100% of CPU (especially when it is infinite loop) or does not use CPU and does not change RAM usage at all (Actual hanging). Still it is difficult to make sure if the software hangs or not. The above means that usually 1 dump is not enough because if that is Infinite Loop – the developers will see that software is working and there is no problem inside. So in order to troubleshoot application lockups you need about 5 dumps collected one after another. A Process Monitor Log will also be useful especially if it actually turns out to be an Infinite Loop.
Please note that an application lockup does not necessarily mean the software is completely unresponsive. A process can hang (e.g. service_process.exe hangs and a backup is stuck), but you can still browse vaults, create new plans etc.
Define the hanging process using Windows Task Manager. In some cases multiple processes are involved in an operation. In this case the hang of 1 process can be caused by some operations in another process. In this case you need to collect memory dumps of all processes involved in the operation. E.g. if a backup to Acronis Storage Node hangs, you need to collect a dump of service_process of the agent as well as StorageServer.exe process on ASN machine.
