amandad

• Addr 0.0.0.0: hostname lookup failed

amcheck

• Access as localuser not allowed from remoteuser@remotehost
• Amcheck cannot login as the amanda user
• Configuration keyword expected

• Numerical argument out of domain
• Port NNNN is not secure
• Selfcheck request failed
• Why does amcheck fail while amdump succeeds?
• Splitsize too small

amdump

• Tar dumps every file in a level-1 backup after a hardware change
• Amdump Only Creates Incremental Dumps in Holding Disk
• Amdump fails to create level 0 dumps
• Amdump is terribly slow

• Data timeout
• Disk offline
• Dump returned 1
• Dump larger than available tape space
• Dump size is the same regardless of the backup level
• Dumps way too big, must skip incremental dumps
