Why does Jira ask if I want to re-index every time we run a backup?

[carl sjoquist]

We have a cron job that uses fsarchiver to backup the JIRA VM.  It stops these services 

'jira', 'jira-davmail', 'mysql' to run the backup and then restarts them after the backup. 

Everytime I go into Jira admin, it says that "Plugins" has changed, and notes the time (which

is the time of the backup) and asks if I want to re-index... Any thoughts on why?

Does your backup process touch the files in the home directory in any way?  And are you backing up the database with the database tools?

[carl sjoquist]

The backup does an fsarchiver backup of the VM's boot and JIRA filesystems, but mounts them as read-only.   Only using fsarchiver, no database tools used.

My guess is that the read-only access is being caught as a change to the data, so it's asking for a rebuild.
