Opening split tar.gz file

[Moganero]

I downloaded a backup from my server that was tar.gz compressed and also split into 2. The file names are foo.tar.gzaa and foo.tar.gzab

PA opens foo.tar.gzaa but says that foo.tar.gzab does not appear to ba a valid archive. it also suggests too open the last files in a series, which, as far as I know, gzab is.

Unusual filenames for split archives.
How did you “split them” originally?

Yes, how the files are splitted? Using gzip or some other file-splitter utility?

… since, I see this for the first time.

The backup utility on the the server splits the backup files if requested (various file-size otions). It’s a linux server and has 4PSA Client Backup installed on it. That’s all I know!

“foo” isn’t the actual name - that was too long to bother typing, the extensions were as they were generated by 4PSA Client Backup.

Sorry, don’t know this utility.

Yes, I understood that, ‘foo’ wasn’t the strange bit - it is the extensions, .gzaa; .gzab etc.

I guess ( ) that it may be a simple file splitter, not a “compression” splitter. If so, maybe you just use a “Join” utility to combine them again into single tar.gz file.

Of course, copy them before trying this - just in case.

This is not standard splitted GZIP archive, nor GZIP supports spliting. So I think this backup utility splits files in it’s own way - just file/size splitting.

You can create joined archive even under command line:

copy /b file.gza + file.gzb + file.gzc file.gz

and then open file.gz. Try this.
