How to backup/restore directory /dev with Unix Agent?

[Holger_Isenberg]

The directory /dev is omitted with Backup Exec and Unix Agent (both 10.0). although the entry with SystemExclude=/dev in ralus.cfg was removed and all restarted.

How can I include /dev with all static entries in the Unix backups?

[Rucha_Abhyankar]

Hello,

-- What version of Unix are you using ?
-- Are you getting any error message?

-- Go to Tools>Options > Linux/Unix

-- Select the "Follow local mount points" and "Follow remote mount points"

-- Restart the Backup exec services.

-- Try doing a backup now.

Thanks for reply!

I'm using RALUS on "SuSE Linux Enterprise Server 9" and "Debian/GNU Linux 3.1". On both systems no files in "/dev" are written to the backup.

In Options -> Linux/Unix "Preserve timestamp" (1st in list, translation from German version), "Follow local mount points" and "Follow remote mount points" are checked.

All Backup Exec services has been restarted numerous times during recent days without changes.

There is no error in the logfile when starting with:
beremote --log-file /var/log/veritas.log

Entries with "/dev" in logfile show that /dev ist scanned by Veritas Server but no file appears in /dev when viewing the file list during restore selection.

grep "/dev/" /var/log/veritas.log:

When analyzing the logfile it looks like /dev is hardcoded for exclusion in the Backup Exec server or unix agent. This is the logfile on SUSE 9 (hostname linux64) when only /dev is selected for backup:

Hello,

Was this file copied to the Linux server before backup? If yes, refer to the following technote:

Title: Modified time backup does not back up new files copied to the UNIX / Linux server when using Remote Agent for Linux and UNIX (RALUS).
http://support.veritas.com/docs/275020

In case you are not using the latest revision for 10.0, ie 5520, download and install it from the following link:

VERITAS Backup Exec (tm) 10.0 rev. 5520 for Windows Servers Installation Files
http://support.veritas.com/docs/277181

Also install the following hotfix:

10.0 5520 - Hotfix 16 - Remote Agent for Linux/UNIX Servers (RALUS) update - Authentication Vulnerability
http://support.veritas.com/docs/278471

If the problem persists, revert with details.

Note : If we do not receive your reply within two business days, this post would be marked ‘assumed answered’ and would be moved to ‘answered questions’ pool.

I have made some tests now with creating new files below /dev, with no success. As the problem occurs with a full backup, so the file creation date should be irrelevant.

As visible in the logfiles these hardcoded (into RALUS) exclusions are used:
56c65bb0 Mon Sep 12 14:20:59 2005: \dev\* /s
56c65bb0 Mon Sep 12 14:20:59 2005: \xfn\* /s

Is it possible to overwrite these hardcoded exclusion lists?

We use static /dev directories, no devfs, so backup and restore should be no problem.
