F5 automated backup script not removing ucs archives/executing post copy clean up commands.

I've installed the https://devcentral.f5.com/codeshare/complete-f5-automated-backup-solution components and when utilizing the scp option have noticed that, although the archives do get copied to remote storage, the /var/local/ucs archives are not being cleaned up. I've seen posts which recommend changing from exec rm -f BACKUPDIRECTORY/$fnameBACKUPFILESCRIPTEXTENSION to exec rm -f BACKUPDIRECTORY/${fname}BACKUPFILESCRIPTEXTENSION which did not help.

 

To me it appears that once the call to execute the bash script, which handles the scp, is performed it never properly returns back to the calling script.

 

I'm basing this on the fact that neither /var/local/usc archives or the /var bash script are ever cleaned up. The commands to remove them immediately follows the call to the bash script.

 

I've modified the command that builds the scp.sh bash, appending the clean up commands to the end of it, so that the clean up happens w/in the bash script before it returns back to the calling script.

 

Before: exec echo -e "put()\n{\n\tfields=\"username server directory\"\n\ti=1\n\tf5masterkey=\$(f5mku -K)\n\tfor current_field in \$fields ; do\n\t\tsedcommand=\"\${i}p\"\n\t\tcurrent_encrypted_value=\$(sed -n \"\$sedcommand\" $configfile)\n\t\tcurrent_decrypted_value=\$(echo \"\$current_encrypted_value\" | openssl aes-256-ecb -salt -a -d -k \$f5masterkey)\n\t\teval \"\$current_field=\$current_decrypted_value\"\n\t\tlet i=\$i+1\n\t\tunset current_encrypted_value current_decrypted_value sedcommand\n\tdone\n\tsed -n '4,\$p' $configfile | openssl aes-256-ecb -salt -a -d -k \$f5masterkey > /var/tmp/scp.key\n\tchmod 600 /var/tmp/scp.key\n\tscp -i /var/tmp/scp.key BACKUPDIRECTORY/${fname}BACKUPFILESCRIPTEXTENSION \${username}@\${server}:\${directory}\n\trm -f /var/tmp/scp.key\n\treturn \$?\n}\n\nput" > $scriptfile

 

After: exec echo -e "put()\n{\n\tfields=\"username server directory\"\n\ti=1\n\tf5masterkey=\$(f5mku -K)\n\tfor current_field in \$fields ; do\n\t\tsedcommand=\"\${i}p\"\n\t\tcurrent_encrypted_value=\$(sed -n \"\$sedcommand\" $configfile)\n\t\tcurrent_decrypted_value=\$(echo \"\$current_encrypted_value\" | openssl aes-256-ecb -salt -a -d -k \$f5masterkey)\n\t\teval \"\$current_field=\$current_decrypted_value\"\n\t\tlet i=\$i+1\n\t\tunset current_encrypted_value current_decrypted_value sedcommand\n\tdone\n\tsed -n '4,\$p' $configfile | openssl aes-256-ecb -salt -a -d -k \$f5masterkey > /var/tmp/scp.key\n\tchmod 600 /var/tmp/scp.key\n\tscp -i /var/tmp/scp.key BACKUPDIRECTORY/${fname}BACKUPFILESCRIPTEXTENSION \${username}@\${server}:\${directory}\n\tcp /var/tmp/scp.key /var/tmp/scp.key.bak\n\trm -f /var/tmp/scp.key\n\trm -f BACKUPDIRECTORY/${fname}BACKUPFILESCRIPTEXTENSION\n\trm -f $scriptfile\n\treturn \$?\n}\n\nput" > $scriptfile

 

This seems to work but I was wondering if anyone else has encountered this issue and has a better solution?

    Thanks John. Any updated solution for the cleanup? I am using: f5.automated_backup.v3.1.9

    Please advise.
