Re: [Bacula-users] error about MySQL-dump file when using bpipe

Hello Silver,

Hello Silver [2],

Please read: http://bacula.us/using-bpipe-to-stream-dumps-vm-clones-and-another-data-to-your-backup

bpipe reads a command data that is directed to stdout and stores in backup with the name you put in the 2nd variable (fifo path) => I hope is what you are trying to achieve with your scripts. While in restore Bacula uses the last bpipe configuration variable (command) to read from stdin and restore your data with the application of your choice. I never saw a bpipe usage documentation with scripts, but with commands directly. E.g.: Plugin = “bpipe:/mnt/fifo/heitorfaria.sql:mysqldump -u root -ppasswd –databases heitorfaria:mysql -u root -ppasswd″

The beauty of bpipe is you don't need local disk space to generate the dumps since fifos actually don't hold data (it just streams it to an end) and you may also automate application restore directly to it.

I recorded some videoclasses that you can find in the same URL post I provided.

JobId 54542: Error: /srv/mysqldump.sql mtime changed during backup.
JobId 54542: Error: bpipe-fd: Error closing for file /srv/mysqldump.sql: 268435583
...
  Termination:            Backup OK -- with warnings

The same error? Have you checked permissions?

After creating those folders, those errors still appeared. Any other ideas?

Aha, I indeed didn't have /mysql directory. Thanks a bunch! :)

PS. Script permissions are correct as otherwise the dump wouldn't have been created.

Hello Silver,

Does the /mysql directory exist? It must.
Make sure also bacula-fd daemon OS user has proper permissions to run the scripts

Hi.

I'm backing up MySQL databases from several servers with Fileset line:
     Plugin = 
"bpipe:/mysql/mysqldump.sql:/etc/bacula/scripts/mysqldump.sh 
mydb:/etc/bacula/scripts/mysqldump.sh -R"

FD on some of those servers give the following error:
     Warning: Cannot stat file /mysql/mysqldump.sql: ERR=No such file or 
directory

I've confirmed that actually the MySQL database is still backed up and 
can be restored too. So why the error? Anybody knows or can guess?
