This article describes the Tape Management functionality, settings, contains correct and incorrect usage examples and provides troubleshooting steps for issue resolution.
In some rare cases there can be some issues with Tape drive detection in Acronis Media.
You booted machine from Bootable Media. In tape management you click on "Detect tapes" and no (or not all) tape drive(s) appears in the list.
Follow step-by-step instructions below to troubleshoot the issue.
How to force tape detection
Click "Detect tape devices" to update the information about the attached tape devices
Following tools should be used to analyze the status of the tape device on a system, check device's details, work directly with a tape device and view the contents of an ARSM (Acronis Removable Storage Management) database.
You may be asked to provide the output or the result of one of these tools while troubleshooting issues with tape devices.
To list the installed tape drives:
Create a .bat file to run inventory before backup
Acronis Cyber Backup products do not take into account tape hardware compression while calculating space on tape media.
During backup to tape you get the following interaction "Cannot find tape to continue backup". You have a tape with free space in the drive or in your library, but after clicking on "OK" you see the interaction come back.
The root cause of the issue is that the available tapes are not in the Tape Pool specified as backup target.
- You back up a machine to a tape,
- Backup fails with:
Data are absent in cache
- You created a backup to a tape directly attached to a machine with Agent for Windows/Agent for Linux,
- You added the same tape as managed location to a Storage Node;
- Recovery or browsing archives from the tape via Storage Node fails with:
The storage node cannot access backups created in an unmanaged location
Product design limitation. Currently recovery of backups created by Agent on tape by Storage Node is not supported.
You can use one of the following workarounds:
Activity (e.g. backup or replication to tape) fails with the following error:
Cannot use the tape drive without a properly installed driver
- You run backups to tape drive.
- Data to backup is enough to fit one backup to one tape, e.g. 3 GB of data and 5GB tape
- You set up cleanup rules to keep 1 backup and run cleanup rules before backup:
If the tape contains an earlier backup, backup operation fails with an error similar to:
- You installed Acronis Cyber Backup 12.5 Update 4 (build 12730 or higher)
- When you try to open an encrypted backup on tape to browse files/folders, you are not prompted for a password.
- You receive the following error:
Password is required
- You deploy a virtual appliance to ESXi host
- You create an Entire VM backup plan to tape (either connected directly or via Storage Node) and activate Enable file recovery from disk backups stored on tapes backup option
- Backup is created successfully
- When you attempt to recover files from this backup, no files/folders are shown. Only Partition 0 empty folder is shown in the backup:
Backup to tape fails with the following message:
No more data is on the tape
New tape is used to continue backup when there is free space on previous tape.
Backup archive uses more tapes than required by its size: e.g. 14GB backup archive uses 17 tapes of 1 GB size.
Tape rescan finishes with error:
Cannot read data from one of the tapes. Ensure that all the tapes are online and not corrupted
