Raul:

Errno #28 is 'ENOSPC' --- No space left on device.

Well-behanved code will report 'errno' with the numeric value or the corresponding mnemonic name.

See '/usr/include/sys/errno.h' for a complete listing.

thanks james
How see the size in a folder or the left size ?

[Steve Lewis]

That output shows all the signs of being an Informix Online backup (ontape or previously called tbtape). It is not tar but IBM Infomix proprietary format. The errno is as JRF indicated.

That being the case you need to change the parameter TAPESIZE in your $ONCONFIG (if my memory serves me it was called tbconfig.xxxx in v5) to make the TAPESIZE smaller.

In older versions you had to guess how much data you could fit onto a tape - including hardware compression, which could vary depending on the type of data in your database.

Now in Informix version 9.40 and 10.00 you can set TAPESIZE to 0 and it will fit in as much as it can to fill the tape up before asking for a second tape.

My guess is that people previously had kept increasing the tape size, until it got too big.

If you want your backup to fit onto just one tape then you need a bigger tape drive, or consider other options altogether.

thanks to all.
Previously it was installed a DDS3 and now a DDS2 tape. There is configured any parameter in informix to work with 2 tapes??.
