Backup impossible because of sliced backup code in EBox/EBackup.pm -- tentative solution attached

[fulvio@…]

The merge of revision 19033 appears to have introduced a bug which makes impossible to perform scheduled backups. Here is the quiet error:

Undefined subroutine &EBox::Logs::SlicedBackup::archiveDir called at /usr/share/perl5/EBox/EBackup.pm line 336, <GEN1> line 1205.

And here the stacktrace:

Undefined subroutine &EBox::Logs::SlicedBackup::archiveDir called at /usr/share/perl5/EBox/EBackup.pm line 328.
 at /usr/share/perl5/EBox/EBackup.pm line 328
	EBox::EBackup::_autoExcludesArguments('EBox::EBackup=HASH(0x962bbd0)') called at /usr/share/perl5/EBox/EBackup.pm line 292

	EBox::EBackup::remoteArguments('EBox::EBackup=HASH(0x962bbd0)', 'full') called at /usr/share/ebox-ebackup/ebox-remote-ebackup line 131

both the result of invoking /usr/share/ebox-ebackup/ebox-remote-ebackup --full .

Line 328 of EBox/EBackup.pm contains the following text:

my $slicesDir = EBox::Logs::SlicedBackup::archiveDir();

The subroutine doesn't appear to exist, so I cobbled together some code to access that configuration value mirroring the code in EBox/Logs/SlicedBackup.pm

I believe a correction to the code in question to be necessary and quite urgent, as it breaks completely the current backup functionality.

Hi fulvio,

the missing subroutine is present in the last version of the ubuntu package 'ebox'. To avoid this problem a dependency in the correct version of 'ebox' was added to the ebox-ebackup modulem so surely with a update your problem will be fixed. So tou know the drill:

$ apt-get update
$ apt-get install ebox ebox-ebackup

If after the update you have the same problem, please attach your ebox & ebox-ebackup ubuntu version numbers and we will look into it.

[fulvio@…]

My bad. I looked at the current code base looking for that sort of change but obviously I missed it. I'll update the ebox package ASAP and report back.

Thanks again for the celerity of the answer.

After updating

$ apt-get update $ apt-get install ebox ebox-ebackup

/usr/share/ebox-ebackup/ebox-remote-ebackup --full is giving below error:

Reconnecting to redis server... at /usr/share/perl5/EBox/Config/Redis.pm line 541, <GEN4> line 1. -bash: GEN4: No such file or directory

Hi Koti. I need a bit more of information. First. What are you backup setting?. Next. Can you retry the command and have a look to the output of /var/log/ebox/ebox.log ?. There it could be useful information to hunt down this error

We can't reproduce this with the packages upgraded. Reopen if you can provide detailed steps on how to do it.
