Data Backup and Recovery.pdf
Data Backup and Recovery.pdfAshraf Hossain Data backup is important for protecting organizations from data loss. There are several key steps to effective data backup: identifying important files to backup, copying files to a secondary storage location like an external hard drive or cloud, and repeating backups on a scheduled frequency. When planning backups, considerations include the backup method, what types of files to backup, backup frequency, storage location, security of backup data, and retention of backup versions. Common backup methods are locally-managed backups using software or cloud-based vendor-managed backups. Security of backup data is also important to prevent unauthorized access to backed up files.

An Analyzing of different Techniques and Tools to Recover Data from Volatile ...ijsrd.com Computer forensics has recently gained significant popularity with many local law enforcement agencies. It is currently employed in fraud, theft, drug enforcement and almost every other enforcement activity. There are many relatively new tools available that have been developed in order to recover and dissect the information that can be gleaned from data storage area like hard-disk, pen drive, etc. it's all like a volatile memory, but because this is a relatively new and fast-growing field many forensic analysts do not know or take advantage of these assets. Memory like Volatile memory may contain many pieces of information relevant to a forensic investigation, such as passwords, cryptographic keys, and other data. Having the knowledge which type of method use and tools needed to recover that data is essential, and this capability is becoming increasingly more relevant as hard drive encryption and other security mechanisms make traditional hard disk forensics more challenging. This research will cover the theory behind volatile memory analysis, including why it is important, what kinds of data can be recovered, and the potential pitfalls of this type of analysis, as well as techniques for recovering and analyzing volatile data and currently available toolkits that have been developed for this purpose.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.

Who Watches the Watchmen (SciFiDevCon 2025)
Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

Explaining GitHub Actions Failures with Large Language Models Challenges, In...ssuserb14185 GitHub Actions (GA) has become the de facto tool that developers use to automate software workflows, seamlessly building, testing, and deploying code. Yet when GA fails, it disrupts development, causing delays and driving up costs. Diagnosing failures becomes especially challenging because error logs are often long, complex and unstructured. Given these difficulties, this study explores the potential of large language models (LLMs) to generate correct, clear, concise, and actionable contextual descriptions (or summaries) for GA failures, focusing on developers’ perceptions of their feasibility and usefulness. Our results show that over 80% of developers rated LLM explanations positively in terms of correctness for simpler/small logs. Overall, our findings suggest that LLMs can feasibly assist developers in understanding common GA errors, thus, potentially reducing manual analysis. However, we also found that improved reasoning abilities are needed to support more complex CI/CD scenarios. For instance, less experienced developers tend to be more positive on the described context, while seasoned developers prefer concise summaries. Overall, our work offers key insights for researchers enhancing LLM reasoning, particularly in adapting explanations to user expertise.

- 3. Introduction Memory in the context of computing generally refers to storage, where data and programs are stored for the computer to access.
- 4. Types of Memory There are different types of memory in a computer system. RAM, or Random Access Memory, is volatile and temporary. On the other hand, storage devices like hard drives and solid-state drives are non-volatile and retain data even when the power is off.
- 5. File Deletion When you delete a file from storage, it is not immediately erased. Instead, the operating system marks the space occupied by the file as 'available' or 'free,' allowing it to be overwritten by new data.
- 6. Recovery Tools Until that space is overwritten, the original data may still be recoverable using specialized tools. Forensic tools like Foremost and Autopsy are designed for this purpose.
- 7. How Recovery Tools Work ? These tools operate by scanning the storage medium for data that is not associated with any file or directory entry. They can identify and reconstruct data based on patterns and structures, even if the file system has removed the reference to that data.
- 8. File Recovery Process • Let's break down how file recovery works: • - Deletion: When you delete a file, the OS marks the space as available for new data. • - File Recovery Tools: Tools like Foremost and Autopsy search for data not linked to any file system entries. • - Data Reconstruction: The tools identify patterns and structures in the data. • - Overwriting Risk: If the space is overwritten by new data, recovery becomes challenging.
- 9. Factors Affecting Recovery The effectiveness of file recovery depends on factors like how much new data has been written to the storage device since the file was deleted.
- 10. Enhancing Data Security To enhance data security, consider using secure deletion methods or encryption tools when disposing of sensitive information permanently. Some file systems may also have features like 'trim' or 'secure erase' to help securely delete data.
- 11. Conclusion In conclusion, understanding how memory works and the risks associated with file deletion is crucial for maintaining data security in computing
