DB2® database systems support some backup and restore operations between different operating systems and hardware platforms.
A database backup from one platform family can only be restored on any system within the same platform family. For Windows operating systems, you can restore a database that was created on DB2 Version 10.1 on a DB2 Version 10.5 database system. For Linux and UNIX operating systems, as long as the endianness (big endian or little endian) of the backup and restore platforms is the same, you can restore backups that were produced on down level versions.
Platform | Endianness |
---|---|
AIX® | big endian |
HP on IA64 | big endian |
Solaris x64 | little endian |
Solaris SPARC | big endian |
Linux on zSeries | big endian |
Linux on IBM® Power Systems™ | big endian |
Linux on IA-64 | little endian |
Linux on AMD64 and Intel EM64T | little endian |
32-bit Linux on x86 | little endian |
The target system must have the same (or later) version of the DB2 database product as the source system. You cannot restore a backup that was created on one version of the database product to a system that is running an earlier version of the database product. For example, you can restore a DB2 Version 10.1 on a DB2 Version 10.5 database system, but you cannot restore a DB2 Version 10.5 backup on a DB2 Version 10.1 database system.
