permissions problem while using 'svnadmin hotcopy'

[Vivek Payala <vi...@persistent.co.in>]

Hello,

 

I have scheduled my SVN repositories to be backed up using 'svnadmin
hotcopy'. I wrote a small wrapper script which gets the list of SVN
repositories and backs them one after the other. However I observed that
after the hotcopy script execution is over my source repositories group
ownership becomes read/execute, which earlier used to be 'rwx'. I thought
hotcopy is supposed to take online backups. But if this is the case I would
have problems taking backup using hotcopy. Could you please let me know how
to fix this.

 

I am pasting my script below for reference.

 

 

#!/usr/bin/perl

my $svnreporoot = "\\/usr\\/local\\/svnroot";

my $backuppath = "/home/svn/backups_svnroot";

my @svn_reps = glob("$svnreporoot/*");

my @mods_bkp;

 

my $sysCmd = "rm -rf $backuppath/*";

system $sysCmd and die $!;

 

for my $svn_repo_path (@svn_reps)

{

        my @svnModNames = reverse (split /\//, $svn_repo_path);

        my $modName = shift @svnModNames;

        push @mods_bkp, $modName;

        print "Backing up $modName \n";

        $sysCmd = "svnadmin hotcopy $svnreporoot/$modName
$backuppath/$modName";

        system $sysCmd;

}

 

 

 

 

Thanks,

What is the umask for the user that runs the backup script? Is it set to
0022 or something like that? The umask can affect the directories that are
created during the hotcopy.
