Hi, I want to migrate my OpenSim MySQL database from Linux to Windows
and vice versa (for traveling reasons) using the MySQL Admin's SQL dump
( MySQL Admin Backup) feature.
Is there anything special that I need to know or to look out for when
doing this (besides making sure Max Packet Size is set to 16 MB on the
target system)?
The way I normally do my database backup in the Linux environment is to
shut down the OpenSim server, go to the backup tool in MySQL Admin,
create a backup project (if it doesn't already exist) for my OpenSim
schema making sure all the tables are selected for backup. Then I go
into advanced options and click on Normal Backup, and check Complete
Backup and run the backup to save my database to a .sql file. This
method has worked perfectly fine for me under Linux with no data loss
after a restore from backup that I can tell. I have even restored my
database to a Windows environment from a Linux created MySQL dump file
with no problems that I can see.
My concern is creating a database backup in a Windows environment and
then restoring it to Linux (or even another Windows environment). Would
this, under normal circumstances, cause data loss?
The reason I ask is: I have successfully been able to restore my Windows
created SQL dump file to Linux and other Windows systems running XP...
But the moment I try to restore my database to a Windows 7 system I get
an error that says "Object Type not recognized" (or it might have said
Object Type not Found, I don't remember off the top of my head) and the
restore fails.
In a nutshell, is it safe to port my backups between different operating
systems like this? Or am I better off creating OARs of my regions and
IAR of my inventory(s)? I always make both OAR/IAR and SQL dump backups
just to be safe, but I would like to know.
Any suggestions and/or tips would be much appreciated! =)
