The backup is done on the SSH console by using the SVN dump command specifying a file into which should be saved.<\/p>\n\n\n\n
$ svnadmin dump \/path\/to\/repository > svnexport.dump<\/p>\n\n\n\n
The created file svnexport.dump now contains the complete repository with all revisions.
Please note that no hooks are secured with this SVN backup. These are located in the folder \/ PathToRepository \/ hooks and should be saved manually.<\/p>\n\n\n\n
The import of the dump file is just as easy, but of course must be a existing repository. If the SVN repository is not yet available use svnadmin create \/path\/to\/repository.
Furthermore, it does not have to be imported in the same SVN repository path as the path from which the SVN repository was exported.<\/p>\n\n\n\n
$ svnadmin load \/path\/to\/repository < svnexport.dump<\/p>\n\n\n\n
As usually the dumps can be very large files, it is advisable to compress the dump. This can be done in a simple line at the command shell and this saves typically more than 50% of disk space.<\/p>\n\n\n\n
svnadmin dump \/path\/to\/repository | gzip -9 > svnexport.dump<\/p>\n\n\n\n
The restore of a gzip compressed SVN repository is also possible as a simple one-liner.<\/p>\n\n\n\n
gunzip -c svnexport.dump | svnadmin load \/path\/to\/repository<\/p>\n\n\n\n
Backing up is also done on a console using SSH svnrdump.
All you need is the URL of the repository, and as before, the file name for the dump.<\/p>\n\n\n
svnrdump dump http:\/\/domain.tld\/repo > svnexport.dump<\/span><\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\nIf you need to authenticate with user and password against your SVN repository, use this command.<\/p>\n\n\n
svnrdump dump http:\/\/domain.tld\/repo > svnexport.dump --username admin --password admin --non-interactive<\/span><\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\nThe created file svnexport.dump now contains all the repository revisions.
The remote SVN export is only possible with remote SVN servers from version 1.4!<\/p>\n\n\n\n
Restore remote SVN repository<\/h2>\n\n\n\n
The import of the dump file is just as easy, but of course it must be existing repository.
For remote import into a SVN server, at least SVN server version 1.7 is required.<\/p>\n\n\n
svnrdump load http:\/\/domain.tld\/repo < svnexport.dump<\/span>\n# or, if the username and password are required<\/span>\nsvnrdump load http:\/\/domain.tld\/repo < svnexport.dump --username admin --password admin --non-interactive<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\nIn the best case will now start the import and all is well.
But in 99.99% of all cases you obtained now this error:<\/p>\n\n\n
svnrdump: E175002: DAV request failed; it's possible that the repository'<\/span>s pre-revprop-change hook either failed or is non-existent\nsvnrdump<\/span>: E175008: At least one property change failed; repository is unchanged\nsvnrdump<\/span>: E175002: Error<\/span> setting property 'rdump-lock'<\/span>:\nRepository has not been enabled to accept revision propchanges;\nask the administrator to create a pre-revprop-change hook<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\nIn this case, the target SVN repository hook ‘pre-revprop-change’ must be installed.
This is of course only possible if you have access to the file system at the target.
In the Hook directory the executable file pre-revprop-change with Exit 0 have to be created.
Use the following one-liner to create the hook script and make it executable.<\/p>\n\n\n
printf '#!\/bin\/sh\\nexit 0'<\/span> > \/path\/<\/span>to\/repository\/hooks\/pre-revprop-change && chmod +x \/path\/to\/repository\/hooks\/pre-revprop-change<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\nNow the remote SVN import should work without any problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
