ARCmain seems to notice whether or not data is compressed or not. If data is compressed at the time of the backup, it gets restored compressed, if not it'll get restored as before, regardless whether the auto compression parameters are on or not.  


Hi Raf,

did you try to switch on compression in your restore script using querybanding adding SET QUERY_BAND 'BLOCKCOMPRESSION=YES;';

I just tested it and my table was compressed during restore :-)

Caution, in the 13.10 manuals there's a bug: Instead of 'BLOCKCOMPRESSION=Y' it's 'BLOCKCOMPRESSION=YES'
