With Sam's Backup and Restore script I need help

@sdetweil

I’ll put this in my own words to see if I’m understanding what I am to do.

Depending on how I create my repository on github will determine my next step.

1. Create respository on GitHub (private is most preferable since I might have private info in my magic mirror config file and I don’t want that public via GitHub).

Note: This process is easier if you create an empty GitHub Repository.

2. If I created an empty GitHub Repsitory:
   2.a.Run the backupscript using the flags on the backup script for repository name, source folder, backup destination folder, github userid, etc.
   2.b. from the backup desitnation folder run the command
   git push

3. if I created GitHub repository with a readme:
   then I’ve made a big mess and shouldn’t have done that. So delete the local folder and github repository and start over.

Results
I ran this

bash -c ./mm_backup.sh -s /home/pi/MagicMirror -b /home/pi/MMbackup2 -r https://github.com/Kayakbabe/MMbackup2.git -u Kayakbabe -e email@mydomain.com -m 5thTry 

And got this:
folder created with name /home/MM_backup
files created inside /home/MM_backup
no folder named MMbackup2

I also tried with -b /home/pi/MMbackup2
and still get home/pi/MM_backup created

i don’t have a folder named MMbackup2 on my pi at all.

I then manually created /home/pi/MMbackup2
ran my command again and still no files were placed in MMbackup2. i tried both =b /home/pi/MMbackup2 and -b MMbackup2 to no avail.

I noticed .git was created in the MM_backup folder along with the files the script created.

I ran git remote -v and get no output. (Just to make sure, i went to a diff local git folder and ran git remote -v and it shows the origins for fetch and pull.) so I think the .git being created in the MM_backup folder isn’t correct.

My questions are:

What is wrong with my flags that my backup folder isn’t being create with the folder name I chose?

Was the backup script supposed to do all the git stuff for me, like the git remote add origin and add files and set the branch and message?
So that, all I am supposed to have to run git push?

Or, am i supposed to now do all the following stuff?

git remote add origin https://github.com/<USER>/<repo>.git
git branch -M main
git push -u origin main

@kayakbabe can you send me the log?

MagicMirror/installers/backup.log

if you are putting the files in your home folder you don’t use the full path

you don’t push, -p will do that.
if you do NOT specify -p then YOU have to do the setup to push, and push. I was trying to save you work
(but as you specified the github repo, I should prompt if you DO want to push)

git remote -v
is from the inside backup folder (see below)

any parms whos default is good you don’t need to specify

also, you don’t clone the scripts to your system, just execute then from the guthub page like install and upgrade (you don’t get my fixes if you clone the repo),
you also don’t contaminate your system in case you have disk troubles and are trying to make an emergency backup

bash -c ./mm_backup.sh -s /home/pi/MagicMirror -b /home/pi/MMbackup2 -r https://github.com/Kayakbabe/MMbackup2.git -u Kayakbabe -e email@mydomain.com -m 5thTry 

should be (-s MagicMirror is default)

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)" -p  -b MMbackup2 -r MMbackup2 -u Kayakbabe -e user@email.com -m "first backup after build finished (or whatever)"

because you did not specify to push, the script did not setup for push (no git remote add )

@kayakbabe
try the latest

I updated the scripts to check for and handle full paths like you used.
and if you specified a repo but did NOT request push, I prompt to discover if you WANT to push this time

if the full path of the backup folder does not exist, I will try to create it,
if it fails, I will report the error, and abort.

-b /foobar

will probably fail, with permission denied
-b /home/$username/whatever

will be used as specified, not jamming $HOME in front

thank you for these testcases which I hadn’t considered…

please use your prior full path command (but use from github)

I also extract the userid from the github repo (and if you specify it thru -u, I check that it matches the one in the url, and abort if not)
hm… I typically build the url from username abd reponame. one thing to check… thx

@sdetweil
what was happening is that no matter if i used the full path or just the folder name like this
-b /home/pi/MMbackup2
-b MMbackup2
the script always used it’s own folder name of MM_backup.

when i tried to run from your repository,
Illegal option '- ’

I tried a local copy pulled a fresh copy from your GitHub and tried again
using -s MagicMirror
and -b MMbackup3

bash -c ./mm_backup.sh -p -b MMbackup3 -r MMbackup2 -u Kayakbabe -e user@email.com -m "second backup after build finished "

the backup folder was still created MM_backup and not MMbackup3.

Then I tried removing the -p option and I get this
bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)” -b MMbackup2 -r MMbackup2 -u Kayakbabe -e email@mydomain.com -m “first backup after build finished (or whatever)”
environment: line 155: [: too many arguments
checking for backup folder MMbackup2
folder doesn’t exist, creating backup folder /home/kelly/MMbackup2
backup folder is /home/kelly/MMbackup2
username specified with -u temp doesn’t match the user in the github repo MMbackup2, aborting

Note i used my correct email, just don’t want it out here to get scraped. And the name and email DO match my github.
I run git remote-v in the folder it created (MM_backup) and there is no git .

@kayakbabe well, all I can say, is I must not have tested it right.
my apologies

try again… all three scripts corrected now
