Setting up a backup system and optimizing server infrastructure

Budget: 7000 UAH Deadline: 5 days

Reliable CRM backups are not just "copying a folder once a day," but a 3-2-1 scheme: automated database dumps on a schedule with rotation, a separate off-site copy (S3/another region), and encryption, plus — most importantly — periodic test restores, because a backup that no one has tried to restore cannot be counted. Concurrently on the server: firewall and closing unnecessary ports, fail2ban, automatic security patches, monitoring of disk/memory/CPU with alerts, basic optimization (database indexes, cache, process limits). In the attachment, I see there are details — I will go through them when you open the view. Questions: 1) what OS, DBMS, and where is it hosted — your own VPS or cloud (AWS/GCP/DO)? 2) do we keep backups here on the server or move them to a separate storage (S3/Backblaze)?

👋 Hello! I'm ready to start working right now. I clearly understand the task and have successful experience in implementing exactly such projects (examples are in the reviews). I will complete the task quickly and without unnecessary questions. Let's discuss the details and get started! 🚀

Budget: 20000 UAH Deadline: 30 days

I will set up backup for the CRM and application: database dumps, user files, configurations, encryption, remote storage, rotation, Telegram/Email notifications, basic server security enhancements, and recovery documentation.

Do you already have a separate test server or local environment where we can check not just the fact of creating a backup, but the complete restoration of the CRM/application from the latest copy to a working state?

Budget and deadlines will be discussed in private correspondence after reviewing the current infrastructure, types of databases, file sizes, server access, storage, Git, and the agreed technological window for production.

Hello, I have worked on a backup system for a CRM with 50+ users and server optimization, which increased speed by 40% and ensured 99.9% uptime.

What is the current architecture of your CRM system and how often do you need to back up data?

I suggest we get in touch; I will provide you with a free technical consultation and we can create a development plan + I will tell you about my team!

Budget: 12000 UAH Deadline: 12 days

Good day, Lera.

The backup scheme for the CRM and application will operate on the 3-2-1 principle: incremental database dumps every hour + full backups daily at 03:00, rsync of media files and configs, GPG encryption before sending to S3/B2 with a rotation of 7/4/3.
Scripts will be wrapped in systemd timers with webhook notifications in Telegram (success + errors separately).
I will conduct a test recovery on an isolated server — confirming data consistency without downtime.

Regarding the server side: auditing slow SQL queries through `pg_stat_statements` / `slow_query_log`, I will add indexes, configure Redis for caching hot endpoints.
Security — UFW with a whitelist of ports, SSH only with keys on a non-standard port, fail2ban with custom jail rules.
CI/CD — GitHub Actions / GitLab CI pipeline with deployment to staging and production.

All scripts, cron configs, and docker-compose will live in Git.
I will provide a README with a Disaster Recovery Plan: a step-by-step guide for recovery from backup.
Work on production will be carried out during the agreed maintenance window to avoid downtime.

Stages:

- Audit of the current infrastructure and requirements gathering
- Setting up backups (DB, files, configs)
- Database optimization and caching implementation
- Strengthening server security (firewall, fail2ban, SSH)
- Setting up CI/CD (optional)
- Recovery testing and documentation preparation

PM: Source code and documentation included. Expand

Hello, Lera!

I administer Linux servers and implement backup systems for production projects — the task is clear.

What I will implement:

Backup of CRM and application:
— Automatic database dumps (PostgreSQL/MySQL) on a schedule via cron with sending to cloud storage (S3-compatible or Backblaze B2).
— Rotation of copies: daily/weekly/monthly, encryption of archives.
— Telegram/Email notifications about the success or failure of the backup.
— Mandatory test recovery to confirm data integrity.

Server improvements:
— Hardening: UFW, fail2ban, SSH only with keys, disabling root login.
— Monitoring: basic health check with alerts on disk/memory/CPU.
— Database optimization: audit of slow queries, indexes, basic configuration parameters.
— Documentation and Disaster Recovery Plan.

All changes in production are made during the agreed technical window to avoid downtime.

Please clarify: what OS and DBMS, is there already cloud storage or does it need to be organized from scratch? I would also like to review the attached document with the details of the technical specifications — please provide access if possible. Expand

Hello! I have reviewed your specifications — the task is clear, and I am ready to take on the execution.

I have experience in setting up automatic backups (cron + bash scripts, sending to S3/Backblaze with rotation and encryption), configuring Firewall, fail2ban, SSH keys, and optimizing PostgreSQL/MySQL (query auditing, indexes, Redis caching). I submit all scripts via Git along with a README and Disaster Recovery Plan — as specified in the requirements.

I will conduct work on production during the agreed technical window to avoid downtime. After completion, I will definitely perform a test recovery from the backup to confirm correctness.

To specify the terms and cost more accurately, please clarify: what stack (OS, DB, hosting) do you have, and is there a separate server for storing backups, or do we need to organize cloud storage from scratch?

Budget: 16500 UAH Deadline: 14 days

Good day. I have experience working with the stack you described. I will be able to complete the task, feel free to reach out.

Budget: 18000 UAH Deadline: 5 days

We have a practically ready approach for backing up CRM and server infrastructure, which can be quickly adapted to your servers and launch the first working phase (:

I would estimate the initial phase at 5 working days - auditing the current scheme, setting up automatic backups, checking recovery, basic security enhancement, and optimizing services.

As for the budget, the estimate is 18,000 UAH for the first phase, more precisely after access to the server structure and the list of services.

Look, there’s a nuance here - backups without a test recovery are almost a ritual, not protection, so I definitely include data recovery checks.

- We will create a backup scheme for the database, application files, and configurations.
- We will set up scheduling, storage, rotation, and error notifications.
- We will check permissions, updates, load, logs, and basic bottlenecks.
- If necessary, we will add simple monitoring automation so that the system doesn’t remain silent during failures =)

What I will need from you:
- Access to the server or hosting within the exchange.
- Information about the stack, database size, where the files are currently located, and whether there is a separate storage for backups.
- Desired recovery requirements - how much data is acceptable to lose and how quickly the system needs to be restored.

I would like to clarify 2 questions:
- Is the database and application currently on one server or distributed?
- Should backups be stored only on the server or also in external storage?

Good day.

I can help with this task. I have extensive experience working with servers, databases, CRM systems, and automating various processes.

I have set up backup solutions for projects where it is important not just to create a backup, but to ensure that the data can actually be restored in case of problems. I have also worked on server optimization, security, monitoring, and eliminating bottlenecks in system performance.

I am ready to review the current infrastructure, assess the scope of work, and propose the best solution without unnecessary complications.

Feel free to write, and we can discuss the details.

Budget: 3500 UAH Deadline: 5 days

Good day!
I have reviewed the technical specifications — I have relevant experience for the entire scope of work. Briefly on the goals:
Backup of CRM and application
- Automatic backups of PostgreSQL/MySQL/MongoDB with encryption and sending to S3/Backblaze B2 via `restic` + cron.
- Rotation according to the daily/weekly/monthly scheme, consistent dumps without locking tables.
- Telegram notifications about status (success/failure) + health check monitoring of the cron execution.

Server improvements
- Basic hardening: UFW, fail2ban, SSH-only-by-key, non-standard port, disabling passwords and root login.
- Audit of slow SQL queries via `pg_stat_statements`, adding indexes, Redis as a cache before the API.
- CI/CD pipelines (GitLab CI / GitHub Actions) for auto-deploy to staging/prod.

Disaster Recovery
- Test recovery after setup — a mandatory step, without it the work is not considered complete.
- README with recovery steps is stored in Git along with the scripts.

Estimated timeframes: 5–10 working days depending on the scope of security and optimization improvements. Backup pipeline with recovery test — 2–3 days.

I am ready to discuss the details — which servers/databases, what is already configured, priorities for tasks.
