Hi,

I successfully ran a partial backup on server A for database X.  
I then copied the partial directory to server B where I tried to prepare the backup for database X.

Server A & B are Solaris SPARC 64-bit.

When I backup and prepare on the same server, everything is fine.  
However, when I tried to prepare the backup on server B, I got the following error.

120106 16:49:05 InnoDB: Starting an apply batch of log records to the database…  
InnoDB: Progress in percents: 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 120106 16:50:28InnoDB: Assertion failure in thread 7 in file log0recv.c line 886

InnoDB: Thread ./prepare\_hot\_backup.sh: line 236: 17380 Segmentation Fault (core dumped) xtrabackup\_50 --prepare --apply-log-only --target-dir=$TMP\_DIR\_PARTIAL

Apart from copying over the partial folder created during the partial backup, do I need anything else? Is this a bug?

Thanks.

Are you using the same cnf file for both servers? Dump a stacktrace of the dumped core so we can see 🙂
