$ ./backuprestore create_backup Backing up to twiki-backup-2012-07-28-20-34.zip: data, -x, .svn/ Backing up to twiki-backup-2012-07-28-20-34.zip: pub, -x, .svn/ Backing up to twiki-backup-2012-07-28-20-34.zip: working, -x, .svn/, /tmp/, /registration_approvals/ ERROR: Can't create backup twiki-backup-2012-07-28-20-34.zip.

Do you know what could be the problem ?

Discussion and Answer

Hello again, I finally manage to perform the backup just setting the location of zip.exe on the path environment of my server. Neverhtless I tried to restore it on the new wiki but I got the following error:

| 2012-07-29 - 12:00 | Insecure dependency in system while running with -T switch at /var/www/twiki/lib/TWiki/Plugins/BackupRestorePlugin/CaptureOutput.pm line 89.

Any clue ?

The taint issue (insecure dependency) needs to be debugged.

Do you use the latest BackupRestorePlugin? It needs to be at least version 2011-09-05.

thanks for the quick reply peter. I was using TWiki-VM-5.1.1-1 virtual machine. I have also downloaded and installed the latest version of BackupRestorePluguin but still I have the same problem. How can i check that I am using the latest version ? how can I debug this problem?

installed version is 22535 (2012-01-13)

Hi again Peter, i finally managed to get rid of that error. The problem is that I was not using the console in the right place, now I can get to console details but I get the following errors:

ERROR: Can't list content of backup twiki-backup-2012-07-29-01-18.zip. error: Zip file too big (greater than 4294959102 bytes) End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. note: /tmp/twiki-backup-2012-07-29-01-18.zip may be a plain executable, not an archive unzip: cannot find zipfile directory in one of /tmp/twiki-backup-2012-07-29-01-18.zip or /tmp/twiki-backup-2012-07-29-01-18.zip.zip, and cannot find /tmp/twiki-backup-2012-07-29-01-18.zip.ZIP, period.

I think this error is because when I created the backup I get the following one:

$ ./backuprestore create_backup Backing up to twiki-backup-2012-07-30-08-55.zip: data, -x, .svn/ Backing up to twiki-backup-2012-07-30-08-55.zip: pub, -x, .svn/ Backing up to twiki-backup-2012-07-30-08-55.zip: working, -x, .svn/, /tmp/, /registration_approvals/ ERROR: Can't create backup twiki-backup-2012-07-30-08-55.zip. zip warning: Permi ssion denied

if i try to restore I get the following message:

NOTE: Nothing to do, no webselected to restore

Seems the backup has not been performed correctly.

What could be the problem of permission denied ?

Thnaks in advance!

I am sorry you run into so many issues with the backup & restore. See BackupRestorePluginDev, the zip utility seems to have a limitation of 4 GB, and it looks like you hit that limit. You probably need to do a manual upgrade. Follow the upgrade instructions at TWikiUpgradeGuide, section Copy your old webs to new TWiki.

-- PeterThoeny - 2012-07-30

Hi Peter, most of the issues I found with the application where more related to my lack of knowledge of twikiinstead of the problems with the application. I also think the main problem is now related with that 4gb restriction so I started to work on manual upgrade. Nevertheless thanks again for your help.
