Backup size

[Veron Le_1]

Hi,

Could you tell me how to know the rest of tape backup size and the size of the backup file. Further, How can I know backup-tape is compressed or not.

Thanks all help me.

Hi,

Compressed or not depends on the device file used for backup.
Information about how much data written to the tape depends on your application. Most backup programs give information about tape usage.

Space left on a tape is impossible to get exact information if compression is used, it depends on compression ratio for your data. It can only be estimated. If compression is not used it is easy:

Total capacity - data written = space left.
