I do make seperate OAR and IAR backups along side my SQL dumps =)<br>
<br>
I was just wondering if there would be any definite data loss when
saving and restoring these SQL dumps across multiple platforms... or if
data loss would be a "freak" kind of thing (i.e. a bug in the My SQL
server or MySQL Admin when it comes to Linux or Windows, or
configuration differences between the default setup of the MySQL server
on Linux vs. Windows, etc). <br>
<br>
Would it be a noticeable thing if data loss did occur such as missing
inventory, or something more subtle that would take a bit of digging to
find; such as missing textures or even "blank" data (i.e. open a
texture and all you see is a white box where the texture should have
been. Or try to play an animation / sound from your inventory and it
won't play)?<br>
<br>
Thank you very much for the suggestions! =)<br>

I would definitely suggest making an IAR backup of every user inventory
and an OAR backup of every region! In that way you have a totally
separate way to transfer the data and at least the opportunity to
recover anything which is corrupted or lost in the transfer!<br>
<br>
I believe there are tutorials on how to automate these backups although
I have not personally tried them. If you have more that 2 or 3 users
and/or 2 or 3 regions then this will significantly reduce the workload.<br>
<br>
It pays to be VER conservative (careful) in making backups since if
information is LOST it can be extremely hard to re-create, finding
something in multiple backups is trivial compared to re-creating
content!<br>

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.<br>
<br>
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)?<br>
<br>
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.<br>
<br>
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?<br>
<br>
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.<br>
<br>
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.<br>
<br>
Any suggestions and/or tips would be much appreciated! =)<br>
