Hello. I heard star is the fastest tar. So I'm trying to run Amanda with star. But the backup results was STRANGE. Below is the part of results:
sendbackup: info BACKUP=APPLICATION sendbackup: info APPLICATION=amstar sendbackup: info RECOVER_CMD=/usr/libexec/amanda/application/amstar restore [./file-to-restore]+ sendbackup: info end | Type of this level 0P dump: partial | Date of this level 0P dump: Wed Aug 17 20:29:10 2016 | Date of last level 0 dump: the epoch ? star: Permission denied. Cannot stat 'file1'. ? star: Permission denied. Cannot stat 'file2'. ... | star: 2 blocks + 0 bytes (total of 20480 bytes = 20.00k). | star: The following problems occurred during archive processing: ? star: Cannot: stat 501, open 0, read/write 0, chdir 0. Size changed 0. ? star: Missing links 0, Name too long 0, File too big 0, Not dumped 0. | star: Processed all possible files, despite earlier errors. | star: '/etc/tardumps' not written due to problems during backup. sendbackup: size 20 sendbackup: end My test environment is that: Amanda server: Ubuntu PC Amanda client: OS is CentOS, the filesystem I want to backup is Lustre (So, this Amanda client is a lustre client). When I tried to run Amanda with star to backup another filesystem(ext4) on the above Amanda client, It was done well. But I want to backup the Lustre filesystem, It doesn't work well. Please advise me about this problem.
