我的磁带是有缺陷还是有其他问题？

Question

我试过用这一行做备份

 tar cvf - --format posix -b 1024 -X /home/user/altro/file.esclude /home/user | openssl aes-256-cbc -salt  -k "pass" | dd bs=40M of=/dev/st0

我的备份的总大小是1TB。

磁带是LTO-5 1.5TB(3tb压缩)

15-30分钟后给我这个错误。

是hw坏了还是tar/dd错误？

Answer 1

我发现“解决方案”是有缺陷的hw，在我的情况下，SAS电缆。更换电缆后工程良好
