Why is /bash_aliases creating this error when sourced?

Question

I have a .bash_aliases file I've been using for a long time. Today I added some commands that are broken into multiple lines (using \).

Since doing that, I can't source the file to reload it. When I do it gets stuck. It just sits there, with a flashing cursor on a new line, and doesn't return me to the command prompt.

Initially doing the source command would return the following error (which I'd not had prior to adding the multi-line commands)

-bash: alias: date: not found
-bash: alias: +%Y-%m-%d-%H.%M.%S: not found

So I changed the line:

    /home/waiheke26/sites/www.waihekehoney.co.nz/backups/wp-files-$(date +%Y-%m-%d-%H.%M.%S).tar.gz \

to

    '/home/waiheke26/sites/www.waihekehoney.co.nz/backups/wp-files-$(date +%Y-%m-%d-%H.%M.%S).tar.gz' \

That stopped that error. But now when I run source ~/.bash_aliases it just sits with a flushing cursor.

UPDATE:

I added a missing " as noted by Spiff in the comments. But now I get these errors when doing a source on the file:

-bash: alias: backup: not found
-bash: alias: OK || echo Database: not found
-bash: alias: backup: not found
-bash: alias: failed: not found

I've gone through the file, and I can't see what the issue is.

QUESTION: What is causing this .bash_aliases file to not update when sourced?

Here's the file (domain name removed)

alias bashupdate="source ~/.bash_aliases";
alias aliases="cat ~/.bash_aliases";

alias wphome="cd /home/waiheke26/sites/www.waihekehoney.co.nz/public";

alias wpsyncfolder="cd /waiheke26/sites/www.waihekehoney.co.nz/backupsync";

alias wpsync="wphome && rsync -va --exclude 'cache' \
    --exclude 'wp-content/uploads' \
    --exclude 'wp-content/cache' \
    --exclude 'wp-content/uploads' \
    --exclude 'wp-content/backups' \
    --exclude 'wp-content/envato-backups' \
    /home/waiheke26/sites/www.waihekehoney.co.nz/public/ \
    /home/waiheke26/sites/www.waihekehoney.co.nz/backupsync/public/ --delete";

alias wptar="wpsyncfolder && tar -zcf \
    '/home/waiheke26/sites/www.waihekehoney.co.nz/backups/wp-files-$(date +%Y-%m-%d-%H.%M.%S).tar.gz' \
    . \
    && echo 'File backup OK' || echo 'File backup failed'";

alias wpbackup="dbbackup && wpsync && wptar && cleanbackups";

# alias wpbackup="wphome && tar --exclude='./wp-content/uploads' --exclude='./wp-content/cache' --exclude ='./cache' --exclude='./wp-content/backups' --exclude='./wp-snapshots' --exclude='./wp-content/envato-backups' -zcf /home/waiheke26/sites/www.waihekehoney.co.nz/backups/wp-files-$(date +%Y-%m-%d-%H.%M.%S).tar.gz . && echo "File backup OK" || echo "File backup failed"';
alias dbbackup="wphome && wp db export --add-drop-table && mv *.sql /home/waiheke26/sites/www.waihekehoney.co.nz/backups/ && echo "Database backup OK" || echo "Database backup failed"";

alias cleanbackups="find /home/waiheke26/sites/www.waihekehoney.co.nz/backups -mtime +7 -delete";
alias cleanbackups-test="find /home/waiheke26/sites/www.waihekehoney.co.nz/backups -mtime +7 -print";

alias wpdbbackup="wpbackup && dbbackup && cleanbackups";

Answer 1

The two issues were as follows:

1. One of the alias definitions was missing it's closing double quotes. (as noted by Spiff in the comments).
2. I had changed around some of the double and single quotes, whilst trying to fix the issue. This resulted in double quotes being nested within double quotes, which is what generated the errors noted in the UPDATE in the question. I needed to either escape those nested double-quotes, or change them the single quotes. (as noted by Spiff in the comments).
