Description

The Backup Files and Directories plugin crashes firewall if /root specified as backup location. The plugin creates its backup at /root/backup and does not exclude the backup directory. This creates a recursive tar which fills all available storage and crashes pfSense.

  • Project changed from pfSense to pfSense Packages
  • Category changed from Backup / Restore to Backup

#3 Updated by Steve Wheeler 5 months ago

I can't replicate this by simply attempting to backup /root.

The backup file is not included in the .tgz.

Testing Backup package version 0.5_3 in 2.4.5p1.

#4 Updated by Marcos Mendoza 5 months ago

I was not able to reproduce the issue either:

path: /root/backup
dir contents: empty
result: archive with empty /root/backup dir

path: /root/backup
dir contents: pfsense.bak.tgz
result: archive with empty /root/backup dir

path: /root
dir contents: default files; empty backup dir
result: archive with default files and empty backup dir

When I tested "path: /", it the failed because it ran out of space (but this is not indicative of a recursive failure).
