#### Functional
##### Before we start, let's make sure we have a fresh environment by running this command `rm -dr logs backups backup_schedules.txt`.
###### Can you confirm that the `backup_manager.py` and `backup_service.py` are present?
##### Run the following command `python3 ./backup_manager.py create "test2;18:15;backup_test2"`.
###### Can you confirm that the `backup_schedules.txt` was created?
##### Run the following command `cat backup_schedules.txt`.
```bash
$ cat backup_schedules.txt
test2;18:15;backup_test2
```
###### Was the schedule created properly, with the same format as the example above?
##### Run the following command `python3 ./backup_manager.py stop`.
###### Can you confirm that the `logs` folder was created and inside of it is the `backup_manager.log`?
##### Now run the command `cat logs/backup_manager.log`.
```bash
$ cat logs/backup_manager.log
[13/02/2023 17:14] "Error: can't stop backup_service"
```
###### Can you confirm that the `backup_manager.log` file contains an error like the one above, stating that the service is already stopped?
##### Create a couple more backup schedules using the command `python3 ./backup_manager.py create "file;HH:MM;backup_name"`.
##### Run the command `python3 ./backup_manager.py list`.
```bash
$ python3 ./backup_manager.py list
0: test2;18:15;backup_test2
1: test3;18:16;backup_test3
2: test4;18:17;backup_test4
```
###### Did you get a result like the one above, with the schedule you created attached with an index at the beginning, on your terminal?
##### Run the command `python3 ./backup_manager.py delete 1`.
```bash
$ python3 ./backup_manager.py list
0: test2;18:15;backup_test2
1: test4;18:17;backup_test4
```
###### Was the task with the index `1` removed from the list like in the example above?
###### Did the task with the index `2` became the task with the index `1` after you removed the old one from the list?
##### Verify that the following command runs without errors: `python3 backup_manager.py start`.
###### Can you confirm that the `backup_service.py` process is running? (For example you could use `ps -ef | grep backup_service`).
##### Now run the command `python3 backup_manager.py start` again.
```bash
$ python3 ./backup_manager.py start
$ cat logs/backup_manager.log
...
[13/02/2023 17:14] Error: service already running
```
###### Can you confirm if the last log is stating that the service is already running? (You can use `cat logs/backup_manager.log` to confirm).
##### Run `python3 backup_manager.py stop` and then `rm -dr logs backups backup_schedules.txt`. Let's create the backup manually.
##### Run the following command by order:
```bash
mkdir testing testing2; touch testing/file1 testing/file2 testing/file3
python3 ./backup_manager.py create "testing;[Current_hour];backup_test".
python3 ./backup_manager.py create "testing;13:11;backup_test".
python3 ./backup_manager.py start
python3 ./backup_manager.py backups
```
Supposing the commands were run at 18:21, here is an example of the commands above:
```console
$ ls
backup_manager.py backup_service.py testing/
$ python3 ./backup_manager.py create "testing;18:21;backup_test"
$ python3 ./backup_manager.py create "testing2;13:11;passed_time_backup"
$ python3 ./backup_manager.py list
0: testing;18:21;backup_test
1: testing;13:11;passed_time_backup
$ python3 ./backup_manager.py start
$ python3 ./backup_manager.py backups
backup_test.tar
$ ls
backup_manager.py backups/ backup_schedules.txt backup_service.py logs/ testing/
$ cat logs/backup_manager.log
[13/02/2023 18:21] Schedule created
[13/02/2023 18:21] Show backups list
[13/02/2023 18:21] Show backups list
$ cat backup_schedules.txt
testing;18:21;backup_test
$ cat logs/backup_service.log
[13/02/2023 18:21] Backup done for testing in backups/backup_test.tar
```
##### Follow the example above and then open the `backup_test.tar` file to ensure that the backup process was successful. Verify that the files are not empty or damaged and that it matches the original directory.
###### Was the backup created successfully?
###### Can you confirm that the `passed_time_backup` was not created successfully because the time has already passed?
##### Run `python3 backup_manager.py stop` and then `rm -dr logs backups backup_schedules.txt`.
##### Create a `.zip` with some folders and files inside it and then replicate the steps you just did above to check if the backup is created successfully.
###### Was the backup created successfully? (open the backup and verify that the files are not empty or damaged and that it matches the original directory.)
### Error handling
##### Verify error handling for incorrect commands and incorrect arguments. For example, confirm that an error message is logged when attempting to run the command `python3 backup_manager.py invalid_command`.
```bash
$ python3 backup_manager.py invalid_command
$ cat logs/backup_service.log
...
[13/02/2023 18:21] Error: unknown instruction
```
###### Was the error message logged correctly?
##### Run `python3 backup_manager.py stop` and then `rm -dr logs backups backup_schedules.txt`. After that run the following commands:
```bash
python3 backup_manager.py stop
python3 ./backup_manager.py create "wrong_format"
python3 ./backup_manager.py backups
python3 ./backup_manager.py start
python3 ./backup_manager.py start
```
```console
$ cat logs/backup_manager.log
[14/02/2023 15:07] Error: can't stop backup_service
[14/02/2023 15:07] Error: malformed schedule: wrong_format
[14/02/2023 15:08] Error: can't find backups directory
[14/02/2023 15:08] Error: backup_service already running
$ cat logs/backup_service.log
[14/02/2023 15:11] Error: cannot open backup_schedules
$
```
###### Can you confirm that all error messages have been saved in the log files like in the example above?
##### Go to the code of the project and check if the creator used `try` and `except` to handle the errors.
###### Did he use `try` and `except` to handle the errors?
