To access /var/log/proxmox-backup/tasks/archive on your PBS server, follow these steps:

1. Access the Log File:

To view the log file directly from the command line, use:

   cat /var/log/proxmox-backup/tasks/archive

1. Filter by Guest (e.g., vm-107):

Use the grep command to filter lines containing a specific guest ID like vm-107:

   grep "vm-107" /var/log/proxmox-backup/tasks/archive

1. Filter by Backup or Restore:

To specifically look for backup operations, use the following command:

   grep ":backup:" /var/log/proxmox-backup/tasks/archive

Similarly, to filter for restore operations, you might look for lines containing :restore:.

1. Show Non-OK Lines Using grep -v:

If you want to display only the lines that do not contain " OK", use:

   grep -v " OK" /var/log/proxmox-backup/tasks/archive

1. Combining Filters:

You can combine these filters for more specific searches, such as finding non-OK backup operations related to a particular guest ID:

   grep "vm-107" /var/log/proxmox-backup/tasks/archive | grep -v " OK" | grep ":backup:"

1. Viewing Output in Columns:

For better readability, you can use less or more to view the output line by line:

   less /var/log/proxmomx-backup/tasks/archive

Or pipe it directly into less for easier navigation:

   grep "vm-107" /var/log/proxmox-backup/tasks/archive | grep -v " OK" | grep ":backup:" | less

By following these steps, you can effectively filter and view specific log entries in the /var/log/proxmox-backup/tasks/archive file on your PBS server.
