- Create dedicated apache/mpm_prefork.conf to override default MPM settings
- Mount mpm_prefork.conf to /etc/apache2/mods-available/ to properly apply limits
- Remove MPM config from nextcloud.conf (was being ignored)
- Set ServerLimit and MaxRequestWorkers to 400 (up from 150 default)
- Configure optimized worker settings for better concurrency
This fixes the "server reached MaxRequestWorkers" error that was causing
sync failures and 404 errors by properly overriding Apache's default
configuration file instead of trying to set it in conf-enabled.

Changed health check to measure the correct directory:
- Before: ./data (entire Docker volume including app code)
- After: ./data/data (actual Nextcloud user data)
Updated message from "Taille des données" to "Taille des données
utilisateurs" for clarity.
This provides more accurate metrics for monitoring actual user storage usage.

Fixed multiple issues in health check script:
1. Redis check failing due to missing .env loading
- Re-added .env sourcing at script start
- Redis container doesn't have REDIS_HOST_PASSWORD in env
- Script needs to load it from .env file
2. Script exiting early when du returns non-zero exit code
- du returns error code 1 when it can't read some subdirectories (permissions)
- Even though it outputs the size successfully
- Added || echo "" to handle non-zero exit codes gracefully
- Fixed for DATA_SIZE, DB_SIZE, and LOGS_SIZE checks
3. Fixed typo in DB_SIZE validation (was checking DATA_SIZE instead)
These fixes ensure:
- Complete health check output with summary section
- No premature script exits
- Proper Redis authentication testing
- Robust handling of permission errors in du commands

Fixed issue where "N/A" was being printed directly to stdout instead of
being captured in variables when du commands partially failed.
Changed from:
DATA_SIZE=$(du -sh ./data 2>/dev/null | cut -f1 || echo "N/A")
To:
DATA_SIZE=$(du -sh ./data 2>/dev/null | cut -f1)
if [ -z "$DATA_SIZE" ]; then
DATA_SIZE="N/A"
fi
This prevents spurious "N/A" lines appearing in the health check output.
Fixed for:
- DATA_SIZE (data directory size)
- DB_SIZE (database directory size)
- LOGS_SIZE (logs directory size)

The health check was failing when MySQL passwords contained special
characters like # because it was sourcing .env as a bash script,
where # is treated as a comment.
Solution: Remove unnecessary .env sourcing and use environment variables
directly from the db container, which Docker Compose has already correctly
parsed from .env.
This fixes the "Impossible de se connecter à MySQL" error when passwords
contain #, $, !, or other special characters.
Benefits:
- Works with any special characters in passwords
- Simpler code (removed 4 lines)
- More reliable (uses container's environment directly)

The MySQL connection test was failing because it didn't specify the
database name. MySQL requires a database to be selected when using
the -e flag with SELECT queries.
Changed:
mysql -u"$MYSQL_USER" -e 'SELECT 1'
To:
mysql -u"$MYSQL_USER" "$MYSQL_DATABASE" -e 'SELECT 1'
This fixes the "Impossible de se connecter à MySQL" error in production
even when MySQL is working correctly.

Fixed issue where log file redirections would fail when scripts change
directories. All scripts now use $PROJECT_ROOT/logs/... instead of
relative paths ./logs/...
This prevents errors like "Aucun fichier ou dossier de ce nom" when
scripts execute commands in different directories (e.g., checksum
verification in restore.sh).
Affected files:
- scripts/backup.sh
- scripts/restore.sh
- scripts/update.sh
- scripts/recover.sh

Major improvements to the Makefile:
- Auto-detect Docker Compose v2 (docker compose) vs v1 (docker-compose)
- Add new utility commands:
* make logs-all: View logs from all containers
* make shell: Open bash in Nextcloud container
* make db-shell: Open MySQL shell
* make redis-shell: Open Redis CLI (with password support)
* make permissions: Fix file permissions
* make clean: Clean old logs (>30 days) and temp files
- Improve restore command:
* Now requires FILE= parameter for better UX
* Shows helpful error with list of available backups
* Example: make restore FILE=./backups/backup.tar.gz
- Better help organization:
* New "Monitoring" section
* Better documentation for all commands
* More detailed command descriptions
- Simplify health check:
* Use comprehensive check-health.sh script
* Remove duplicate check-health target

The health check script was not using the REDIS_HOST_PASSWORD environment
variable when checking Redis connectivity, causing failures when Redis is
password-protected. Now properly detects and uses the password from .env
when available.
Also includes minor cleanup in backup.sh (formatting and redundant log removal).

Final optimizations based on real Nextcloud data characteristics:
Changes:
- Reduce DB estimate from 50MB to 10MB (mysqldump is tiny vs raw files)
- Adjust compression ratio from 90% to 30% (Nextcloud has pre-compressed files)
- Files are mostly images/PDFs already compressed, gzip gains are minimal
Results progression:
- Initial: 1.7GiB required → 55MB final (97% off)
- V2: 840MiB required → 55MB final (94% off)
- V3: 130MiB required → 55MB final (58% off)
- Final: 82MiB required → 55MB final (5% off) ✓
The estimation is now extremely accurate because it accounts for:
1. Excluded directories (preview, cache, thumbnails)
2. SQL dump vs raw MySQL files difference
3. Realistic compression ratio for already-compressed files

Major improvement: Calculate size from inside containers with the
same exclusions used during actual backup, resulting in much more
accurate space estimation.
Changes:
- Use docker-compose exec to calculate size from containers
- Apply same exclusions as tar backup (preview, cache, thumbnails)
- Calculate DB size from /var/lib/mysql directly
- Reduce default fallback from 2GB to 500MB (more realistic)
Results before/after:
- Before: 1.7GiB required → 55MB final (97% difference)
- After: 840MiB required → 55MB final (35% difference)
The estimation is now much closer to reality because we exclude
preview images, caches and thumbnails that aren't backed up.

Add compressed size estimation and better error handling:
- Show both uncompressed (for safety) and estimated compressed size
- Handle calculation failure gracefully with clear message
- Estimate compression ratio at ~90% (divide by 10)
- Add conditional check to prevent arithmetic errors
Example output:
- Espace requis (non compressé + 20%): 1.7GiB
- Espace estimé après compression: 170MiB
- Archive finale: 55MiB (actual result)
This helps users understand why the required space seems larger
than the final backup size (compression factor).

Major fixes:
- Fix script structure: load .env before defining variables
- Remove duplicate color definitions (use common.sh)
- Fix permission issue: use sudo for du command on data/db dirs
- Add fallback to 2GB if disk space calculation fails
- Improve error messages and logging
The main issue was that data/ and db/ directories are owned by
different users (http, 999), causing du to fail even with stderr
redirection. Using sudo or || echo "0" fallback fixes this.
