Acronis Backup products do not take into account tape hardware compression while calculating space on tape media.
- You are using tape drive as backup destination;
- This tape supports hardware compression;
- When hardware compression is switched on, Acronis Backup does not take into account tape hardware compression while calculating space on tape media.
(!) This may result in incorrect display of space available in tape vault as compared to space shown by the tape itself. Please consider tape hardware compression if you see any inconsistency in space shown by Acronis for a particular tape device.
Currently Acronis Backup products do not support tape hardware compression.
You can work around this issue by disabling the hardware compression.
