I have restored tar files > 9GB, but that was on a reiserfs filesystem, and my system has 1GB of RAM. I think I see your problem (someone please correct me if I just read this wrong): >From your original message: > argv[0] = "amrestore" > argv[1] = "-p" > argv[2] = "-h" > argv[3] = "/home/general/testSet1" > argv[4] = "^barracuda$" > argv[5] = "^/junk$" > argv[6] = "20030305" > amrestore: error reading file header: Is a directory > amidxtaped: time 0.006: amrestore terminated normally with status: 2 > amidxtaped: time 0.006: rewinding tape ... > amidxtaped: time 30.105: tape_rewind: rewinding tape: > /home/general/testSet1: Inappropriate ioctl for device You didn't give the right arguments to amrestore, You specified your two flags "-p -h", but then gave a diskname. The next argument to amrestore must be either the tapedevice (e.g., /dev/nst0) or a holding file. You'll notice that it said, "amrestore: error reading file header: Is a directory". This is because it is trying to read the file header from a directory (/home/general/testSet1), rather than a tape. Later it says, "/home/general/testSet1: Inappropriate ioctl for device", because it is then trying to rewind the directory. Clearly this is innapropriate. :) Hope this helps you out. -- ---------------------------------------------------------------- |Christopher Dahn | Software Engineering Research Group,| |3141 Chestnut St. | Feel the SERG! | |Attn: CS Dept., CAT 186 | http://serg.cs.drexel.edu/ | |Philadephia, PA 19104 ------------------------------ ------ |Office (PA): XXX.XXX.XXXX | OpenPGP public key: | |Office (NJ): XXX.XXX.XXXX | http://search.keyserver.net/ | |Fax: XXX.XXX.XXXX | | ---------------------------------------------------------
