Hi,
I unpacked the tar on the backup server itself, which is also the host on
which I used firefox to download the tarfile.
The only tar I found is version 1.23 (corresponding to the debian/testing tar
package 1.23-2.1)
However, my primary problem is not tar. The primary problem is that I have
reproducable crashes in Backuppc, when trying to restore some files of the
backup, while other files can be restored without problem.
I was failing restoration to
o Windows Vista + ntfs + smb
o Windows Vista + ntfs + rsyncd / Cygwin
o Linux (GRML) + ntfs + rsync via ssh + (mounting nfts in rw-mode via
ntfs-3g)
What does work is:
o downloading the "problem file" via tar
o restoring to localhost (Linux (Debian) + rsync via ssh)
I was close to blaming NFTS, but since I can untar the file to NTFS via the
GRML boot, I'm not sure this is right.
