User scsi's response doesn't seem to me to go far eough.
@ratanegr:
The backups are in the form of tarballs, which most PC-based zip/unzip programs can managing, converting them back into directories with contents. If the contents are additional tarballs, simply keep going down through them, using the same program to open them.
Since making a proper tarball could be complex, I'd recommend using ftp to get them back oonto your account later, once you're back.
Plese in the future try to use a better category for your posts; I've moved this one; it's a user issue.
