Error while logging

When using automysqlbackup and/or autopostgresql backup, no logging to a file is being done and an error code of 1 is being returned.

No error is being returned when the following lines are being disabled:

automysqlbackup:#exec 6>&1 # Link file descriptor #6 with stdout.
automysqlbackup:#exec > $LOGFILE # stdout replaced with file $LOGFILE.
automysqlbackup:#exec 7>&2 # Link file descriptor #7 with stderr.
automysqlbackup:#exec 2> $LOGERR # stderr replaced with file $LOGERR.

automysqlbackup:#exec 1>&6 6>&- # Restore stdout and close file descriptor #6.
automysqlbackup:#exec 1>&7 7>&- # Restore stdout and close file descriptor #7.

autopostgresqlbackup:#exec 6>&1 # Link file descriptor #6 with stdout.
autopostgresqlbackup:#exec > $LOGFILE # stdout replaced with file $LOGFILE.
autopostgresqlbackup:#exec 7>&2 # Link file descriptor #7 with stderr.
autopostgresqlbackup:#exec 2> $LOGERR # stderr replaced with file $LOGERR.

autopostgresqlbackup:#exec 1>&6 6>&- # Restore stdout and close file descriptor #6.
autopostgresqlbackup:#exec 1>&7 7>&- # Restore stdout and close file descriptor #7.

The user for which the scripts are running is root and root is allowed to create the log files but that doesn't happen and an error is being return.

What could be the source of this problem and how can this be fixed?
