ChatGPT said:

In Zimbra, the redo log retention period controls how long redo logs (which record mailbox transactions for backup/replay) are kept before deletion.
Here’s how you can view and set the redo log retention period:

Perfect 👍 — here’s how you can automatically delete old Zimbra redo logs after a specific number of days.

🧰 Example: Keep Redo Logs for 7 Days

Run these steps as the zimbra user:

su - zimbra
crontab -e

Then add this line at the bottom:

# Delete redo logs older than 7 days
0 2 * * * find /opt/zimbra/redolog/archive/ -type f -name "*.log" -mtime +7 -delete

✅ Explanation:

• Runs every day at 2:00 AM

• Looks in /opt/zimbra/redolog/archive/

• Deletes files ending in .log that are older than 7 days

🧩 If You Want 30-Day Retention Instead

Just change +7 to +30:

0 2 * * * find /opt/zimbra/redolog/archive/ -type f -name "*.log" -mtime +30 -delete

⚠️ Notes

• Make sure zimbraRedoLogArchiveEnabled is set to TRUE, otherwise no archived redo logs are created:

  zmprov mcf zimbraRedoLogArchiveEnabled TRUE
  

• You can verify the archive path using:

  zmprov gacf | grep zimbraRedoLogArchiveDir
  

• Adjust /opt/zimbra/redolog/archive/ if your installation uses a different directory.
