It seems i am having a issue with mongodump, i think the problem is at the

Exception 'phpbu\App\Exception' with message 'Mongodump failed'
in phar:///usr/local/bin/phpbu/Backup/Source/Mongodump.php:163

backup mongodump: FAILED

Edit:
After some digging i foud this command, witch makes the error, generated by phpbu```
root@ip-172-31-63-218:/root# /usr/bin/mongodump --out '/root/backup/' --host 'localhost' --database 'status'
2016-02-11T03:44:41.287+0000 error parsing command line options: unknown option "database"
2016-02-11T03:44:41.287+0000 try 'mongodump --help' for more information

Hi, looks like the option should be --db instead of --database.
Could you please verify this by executing the command with the changed option.
If that's the case I will release a fix ASAP ;)

[sebastianfeldmann]

I have just released 3.0.2with a fix for the --db option
You can give it a try

$ phpbu --self-update
$ phpbu --simulate

[necenzurat]

Offtopic for a bit, i have this line for the target

<target dirname="backup/mongo" filename="data-%Y%m%d-%H%i.json" compress="bzip2"/>

mongodump generates a "dump" folder with the databases inside,
mongorestore (to import) looks for the "dump" folder

i've successfully used phpbu on mongo with update 3.0.2, but after the archive was generated, when bzip2 -d it made a single file, witch it cannot be used for importing.

Thanks.

The final mongodump directory is getting compressed by the tar command.
You can extract it with this command

$ tar jxvf filename.tar.bz2

[necenzurat]

but, how can i compress the whole dump directory?

[sebastianfeldmann]

If you specify a compressor like you did

<target dirname="backup" filename="mongodata-%Y%m%d-%H%i.dump" compress="bzip2"/>

You should see a file backup/mongodata-20160211-1530.dump.bz2

If not that's not good 😞

[necenzurat]

the backup part it's ok but the restoring part worries me:

ideally, when you extract the bz2 dump should result in a dump dir with the databases

[sebastianfeldmann]

The created mongodump directory is getting compressed with tar so it's getting compressed to a single file.

To uncompresse the file use.

$ tar jxvf mongodata-20160211-1427.dump.bz2

or

$ tar xvf mongodata-20160211-1427.dump

This should work ;)

[necenzurat]

meh, that was my bad 😄
it would be nice if it would prepend the databases dir. would save the hard work of making a dump folder and putting the databases there in case of a restore.

thanks for the help.

[sebastianfeldmann]

You can easily do so with

$ mkdir dump && tar jxvf mongodata-20160211-1427.dump.bz2 -C dump

But I will have a look at the tar command, maybe I can include the compressed folder itself

[necenzurat]

yea i know, but people, especially me are uber lazy.

[sebastianfeldmann]

I know the feeling ;)
