Sonic Systems advertises and sells two backup programs, "Simple Backup" and "BackupMyPC". The prominently mention that compression is available in both progams. What they do not mention is that one cannot RESTORE compressed files. I have called technical support and sales, and their reaction was, "so what do you want from us". How about stopping false advertising?
I have used UltraISO to remove blocks from a backup. Files are 1GB, and have .ibq extensions on them. Can anyone suggest a way to determine what compression algorithm has been used?
I very much need to recover these data, buy commercial services want more than my monthly income (social security disability). If I have to, I'll take out a loan, but not before exhausting all other possible ways of recovering the data.
Thanks very much in advance,
Dan Davison

As there are DOZENS of compression algorithm, "Simple Backup" may use any combination of them. It is not possible to uncompress your file unless the specification of this format is available.

Thanks very much. I will try to find out from their "technical support" department what encoding is being used. As Simple Backup started a Veritas, which was then sold to Symantec, which was then sold to Roxio, which was then sold to Sonic, I'm not really hopeful. I vaguely remember hearing that compression algorithms left "signatures" in their files but that may have been in the IBM 360/370 days.
Any other guesses or pointers would be very welcome!
