i use flexbackup 1.2.1 on a debian sarge.
I do backup with afio and bzip2 on travan tape 4/8 Go Seagate STT8000A.
All my backup process fine :
afio: 145m+690k+0 bytes written in 346 seconds. The operation was successful.
Kilobytes Out 149170
Kilobytes Out 149170
But when i want to decompresss with flexbackup -extract command, afio tell me :
| Logging output to "flexbackup.extract.200608181908.log"
| Trying "mt defblksize" instead of "mt setblk"
| Reading from CURRENT TAPE POSITION
|------------------------------------------------------------
At block 7062477.
|------------------------------------------------------------
| buffer -m 10m -p 75 -s 10k -t -u 100 -i "/dev/nst0" | afio -i -z -x -D \
| /usr/bin/flexbackup -P bzip2 -Q -d -Z -v -b 10k -
|------------------------------------------------------------
buffer (reader): failed to read input: Input/output error
afio: "-": No input
|------------------------------------------------------------
At block 7062477.
I don't understand my problem !!
Somebody can help me ?
i post my flexbackup.conf
Thanks you for your help and sorry for my english, i'm french people

# Archive type? afio, dump, tar, cpio, star, pax, zip, lha, ar, shar

# Example:
# $set{'set1'} = "/home /usr";
# $set{'set2'} = "/dir3 machine2:/dir4 machine3:/dir5";
