Functional

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.

$ 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.

$ cat logs/backup_manager.log
[13/02/2023 17:14] Error: cannot kill the 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.

$ 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.

$ 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? Use python3 ./backup_manager.py listto.

Verify that the following command runs without errors: python3 backup_manager.py start.

Can you confirm that the backup_service.py process is running by using the command ps -ef | grep backup_service?

Now run the command python3 backup_manager.py start again.

$ python3 ./backup_manager.py start
$ cat logs/backup_manager.log
[13/02/2023 17:14] Error: service already running

Can you confirm bu running the command cat logs/backup_manager.log if the log file contains an error like the one above, stating that the service is already running?

Run python3 backup_manager.py stop and delete everything that was created until now, the logs folder and the backup_schedules.txt. Lets create the backup manually.

Run the following command by order:

1- mkdir testing; cd testing; touch 1 2 3; cd ../
2- python3 ./backup_manager.py create "testing;"Current_hour";backup_test".
3- python3 ./backup_manager.py start
4- python3 ./backup_manager.py backups

$ mkdir testing; cd testing; touch 1 2 3; cd ../
$ ls
backup_manager.py  backup_service.py  testing/
$ python3 ./backup_manager.py create "testing;18:21;backup_test"
$ python3 ./backup_manager.py list
0: testing;18:21;backup_test
$ 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 18:20] Schedule created
[13/02/2023 18:20] Show schedule list
[13/02/2023 18:21] Backup 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

Can you confirm that the backup was created successfully? Follow the example above.

Error handling

Verify error handling for incorrect commands and incorrect arguments. For example, confirm that an error message is displayed when attempting to run the command python3 backup_manager.py invalid_command.

$ python3 backup_manager.py invalid_command
Error: unknown instruction

Was the error message displayed?

Run python3 backup_manager.py stop and delete everything that was created until now, the logs folder and the backup_schedules.txt. After that run the following commands:

1- python3 backup_manager.py stop
2- python3 ./backup_manager.py create "wrong_format"
3- python3 ./backup_manager.py backups
4- python3 ./backup_manager.py start
5- python3 ./backup_manager.py start

$ cat logs/backup_manager.log
[14/02/2023 15:07] Error: cannot kill the service
[14/02/2023 15:07] Error: invalid schedule format
[14/02/2023 15:08] Error: [Errno 2] No such file or directory: "./backups"
[14/02/2023 15:08] Error: 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 adn check if the creator used try and catch to handle the errors.

Did he use try and catch to handle the errors?
