Introduction

Acronis software may give errors, freeze or produce other undesired effects when there are issues with parts of the computer environment it operates in:

Examples of error messages in Acronis software, when you would want to check the environment:

Unable to create volume snapshot

Failed to read snapshot

Failed to read from sector...

Failed to read from disk...

Failed to write the snapshot manager volume

Various types of read and write errors

Input/Output (I/O) errors

Errors referencing \\?\GLOBALROOT\Device\...

Cyclic redundancy check (CRC) error

Failed to enumerate directory

WMI ExecQuery failed

MFT bitmap corrupted

Solution

Acronis has developed a free tool that automates the process of checking the environment particularly for Volume Shadow Copy Service (VSS)-related issues: Acronis VSS Doctor. This tool saves time on gathering and analyzing diagnostic information from various sources, including Windows Event Log, but it does not cover all possible root causes and applies to VSS-related issues only.

A more universal approach consists in checking Windows Event Log for issues with computer environment using Windows Event Viewer:

1. Open Windows Start Menu.

2. Type Event Viewer and press Enter:

If Windows Search does not find Event Viewer by name, press the combination of the button with Windows logo on keyboard and R, and run the command evenvwr.msc

3. Windows Event Viewer will open:

4. Navigate to Windows Logs - System:

5. Click Filter Current Log... on the right panel:

6. Mark Critical, Error and Warning checkboxes in the upper part of the window, click OK to apply the filter:

7. At this point you can click OK and review the recent warnings and errors, recorded in the System event log, and look for any information related to the issue observed in Acronis software. Pay special attention to events registered at the time the issue occurred, or just before that:

8. As there may be many unrelated events, you can narrow the search further, by applying the following suggested filter. Click Filter Current Log.. again:

9. Expand Event sources list:

10. Scroll through the list and mark the following items:

Short list (most popular sources of errors):

disk

Disk

Ntfs

Ntfs (Microsoft-Windows-Ntfs)

Ntfs (Ntfs)

11. Click OK and review the filtered list of events. Your further actions will depend on what parts of the environment were reported to have issues and on their current status:

12. When troubleshooting a VSS or WMI-related issue, it is useful to also check warnings, errors and critical events under Windows Logs - Application section. In addition to troubleshooting issues with Windows environment, Application logs are also used to detect application crash and hang events.

Further troubleshooting

Look up the detailed error/warning text, as well as the Event ID number on the Internet. Issues with environment are common and are likely to have a solution or a workaround already documented or described.

If you are not sure if the found errors and warnings could be the cause of the issue with Acronis software, contact Acronis Customer Central with a system report and screenshots of the issue with Acronis, log of the operation in Acronis (if any) and the found records in Windows Event Log.

Introduction

Acronis Survival Kit is a simple all-in-one recovery tool for external drive backups based on Acronis Bootable Rescue Media. 

To recover your computer in case of a failure, you need to have two crucial components—a backup of your system disk and a bootable rescue media. Previously these components were separated, for example, the system backup is stored on an external drive or Acronis Cloud and the bootable media is a small USB flash drive. In Acronis True Image 2019, an Acronis Survival Kit combines both components so that you could have a single device that has everything that you need to recover your computer in case of a failure. It is an external hard disk drive that contains both the Acronis Bootable Media files and a backup of your system partition, entire computer, or any disk backup. Bootable media component is created based on Acronis Bootable Rescue media.

Acronis Survival Kit can be created on external hard disk drive connected via USB with at least 32 GB of free space. During Acronis Survival Kit creation a hidden 2GB(Windows)/ 3.5GB(Mac) partition is created in the beginning of the drive and bootable media components are placed on that partition.

(!) Acronis Survival Kit cannot be created on a USB flash drive.

Supported file systems on external HDD for Acronis Survival Kit creation:

Windows version:

• NTFS
• FAT32
• exFAT
• If the drive has another file system, Acronis True Image 2019 suggests formatting the drive.

MacOS version:

• APFS
• HFS+
• If the drive has another file system, Acronis True Image 2019 suggests formatting the drive.

Solution

On a Windows machine:

To create Acronis Survival Kit, follow the steps below:

1. Make sure your external hard drive is plugged in
2. Launch Acronis True Image and click Add Backup, if needed
3. Select Entire PC or system disk as a backup source. In this example, disk C and recovery partition are selected

4. Click on the right tile to change backup destination and select the external hard drive as a destination. Click on Create Acronis Survival Kit (this option appears only when a suitable external hard drive is selected as a destination)

5. Click Create
   If the external HDD is not a GPT one and has a file system different from NTFS, FAT32, or exFAT, Acronis True Image 2019 suggests formatting the disk. Note that formatting will erase all data on the disk.
6. The bootable part of Acronis Survival Kit is created. Click Back up now to create a disk/Entire PC backup and complete Acronis Survival Kit creation.

7. After Acronis Survival Kit is created, the backup destination icon will change from generic external HDD to Acronis Survival Kit.

On a Mac:

To create Acronis Survival Kit, follow the steps below:

1. Make sure your external hard drive is plugged in
2. Launch Acronis True Image and click Add Backup, if needed
3. Select Entire Mac or system disk as a backup source. In this example, Entire Mac is selected

4. Click on the right tile to change backup destination and select the external hard drive as a destination. Click on Create Acronis Survival Kit (this option appears only when a suitable external hard drive is selected as a destination)

5. Click Create

6. The bootable part of Acronis Survival Kit is created. Click Back up to create a disk/Entire Mac backup and complete Acronis Survival Kit creation.

7. After Acronis Survival Kit is created, the backup destination icon will change from generic external HDD to Acronis Survival Kit.

Symptoms

Backup task fails with the following error:

There is not enough space on the destination drive to perform a backup

Solution

The software detected that there is not enough space on destination to complete the backup.

1. If this is the first time you create a backup, make sure that the selected destination has enough space for the data that you want to backup. Specify a different backup destination or select less data for backup.

2.  If you have previously created backups with this backup task, most likely the destination have filled up with archives. Free up disk space on destination by deleting unnecessary archives as described in Acronis True Image 2019: How to delete old backups.

3. If there are old .TIB files in the destination location that do not correspond to any of backups in Acronis True Image interface, turn off Active Protection temporarily and delete those .TIB files in Windows Explorer to make room for new backups.

4. If you do not know what consumes disk space in the destination location, use a free disk space analyzer tool: DiskSavvy, WinDirStat or any other.

5. Lastly, set up automatic cleanup rules to avoid filling the storage completely: see Automatic Cleanup Rules section in product documentation.

Symptom

All conditions must be true:

1. Act! software and Microsoft SQL Server are installed
2. Acronis True Image does not create a backup. If you click the red exclamation mark at the center of the backup screen, the following error message is displayed:
1. Entire PC and disk/partition backups: Unable to create volume snapshot
2. File and folder backup: Failed to backup file or folder
3. The last modified log file at C:\ProgramData\Acronis\TrueImageHome\Logs\ti_demon contains the following text: VSS writer 'SqlServerWriter' with class ID 'A65FAA63-5EA8-4EBC-9DBD-A0C4DB26912A' has failed to process the snapshot

Cause

Incorrectly configured Microsoft SQL Server, that comes with Act! software

Solution

Change SQL Server(ACT7) service user to Local Service by following the steps below:

1. Open the Windows Start menu, type compmgmt.msc and press Enter on the keyboard
2. Expand Services and Applications​ on the left panel
3. Click on SQL Server Configuration Manager
4. Locate SQL Server (ACT7).
5. Change the service logon from Local System to Local Service:

• Right-click on the SQL Server (ACT7) and select Properties
• On the Log on tab, select Local Service in the Built-in account drop-down menu, then click OK

Verify that the column "Log On As" displays "NT AUTHORITY\LocalService" for "SQL Server (ACT7)" line as shown below:

Introduction

Old backups are deleted automatically according to the rules defined in the backup options. Read "Automatic cleanup rules" section in the user guide: local backups, backups in Acronis Cloud.

The backup menu option "Delete", that has always existed in the program, removes a backup completely, with all of its versions.

Acronis True Image 2019 for Windows introduces a new option for you to have more control over local backups - "Clean up versions". This feature permits deleting just the selected backup versions and their dependencies on demand, without changing automatic cleanup rules and waiting until they are applied.

Solution

1. In the Backup section, click the down arrow icon next to the backup to clean up, click Clean up versions...

2. Clean up backup versions window opens

3. By default, Acronis True Image 2019 selects to delete all version chains, except the last one.
   
   Click here to see what version chain is

   
   

   Version chain is a set of a full backup and all incremental and differential backups, that depend on it:

4. If you want to delete:

• All backup chains except for the last, then click Delete without modifying the selection.

• Specific backup versions, then clear the check boxes next to the versions that you want to keep, and then click Delete. Note that in this case dependent incremental and differential backup versions are marked for deletion as well.

If some of the backup versions are missing (e.g. .TIB files were deleted, renamed or moved in Windows Explorer), the program will detect it and offer to delete broken records and dependencies.

More information

To learn about deleting backups from Acronis Cloud, check the product documentation here.

Symptoms

You receive an e-mail notification with backup log, containing one or multiple lines with "Volume Tracker has failed to find changes on volume..."

Example:

2018-12-20T09:00:10:378-04:00 10916 I000101F8: Pending operation 173 started: 'Creating partition image'.

2018-12-20T09:00:11:190-04:00 10916 I00100000: Volume Tracker has failed to find changes on volume '\\?\Volume{5e2aeab2-ffb3-4dab-8444-54635f6a3367}\'.

Cause

It is a service message that can be safely ignored.

Description

There are the following message types in Acronis True Image logs:

• Informational, identified by letter I in the status code before the text message. They do not represent any problem and can be safely ignored. In our example above the status code before the text Volume Tracker has failed to find changes is I00100000, starting with I - Informational message.
• Warnings, identified by letter W. They should be checked, but are not critical for backup task execution.
• Errors, identified by letter E. Errors usually mean that backup task execution failed and a new backup version was not created.

The message "Volume Tracker has failed to find changes on volume..." refers to the internal mechanics of the backup engine. In certain situations the software can accelerate already fast (incremental or differential) backup even further by knowing what disk sectors have changed since the last backup even before the backup starts. It is normal that sometimes, e.g. on the first backup after computer reboot, the changes on the disk can be calculated only after the backup starts, not before. In such cases the message Volume Tracker has failed to find changes appears in the logs.

The created backup is equally good as if there was no such message in the logs.

Introduction

This article describes how to set up Acronis True Image so that backups are saved to two or more external disks, which could be swapped or rotated on regular basis. For example, backup to disk A on even weeks and backup to disk B on odd weeks. The disk that is not used on a given week is usually kept in a different physical location as an extra layer of protection.

Skip to solution

Background

Consider an example: you have 1 backup task and 2 or more external drives as destination, which you want to swap regularly. You expect that another drive with the same drive letter will be recognized in Acronis True Image as destination automatically, but backup fails with the error message about missing backup destination. The backup failure in this case is expected program behavior.

Each drive has a unique identifier (not to be confused with drive letter), which is saved in the program’s database when a new backup task is created. When you plug in another hard drive and try to run backup in the old task, it won’t be recognized as the backup destination even if the drive letter is the same, because the unique identifier of the new drive is different and doesn't match the information in the database for this task.

Solution

Because Acronis True Image is positioned as a product for home use, the scenario of swapping destination disks is not supported out of the box, but it can be implemented as follows:

1. Rotating external disks with backups requires that each disk that is being rotated has its own backup plan. For example, if there are 3 disks where you store backups, of which only 1 is used at a time, there must be 3 backup plans, each targeting the corresponding disk of the three.
2. If there are earlier created backups, which you would like to continue, make sure they do not span across multiple disks. If they do, delete them in Acronis True Image using the context menu option "Delete", then "Delete entirely".
3. Each backup plan shall be created when the respective destination disk is connected, and the rest of the disks are disconnected.
4. Name each backup plan differently.
5. Do not use "Clone settings" option - create each plan from scratch.
6. Distribute the schedule for backups so each backup plan will be executed only on days and time, when the corresponding disk is connected. E.g."Monthly" - "Every third Tuesday".

More information

Advanced users can script logic to automatically choose the right backup plan to launch, depending on which disk is currently connected. Acronis does not provide technical assistance with such scenarios. An example is given on Acronis forum by Steve Smith.
