Rsync an offline database?

2012-06-27 Thread BillDorrian
Is rsync a good way to make a valid copy of offline database files (TSM, in this case) from one xfs filesystem to another? If so, which options should I use? Once again, the database services would be shut down, so the database would be offline. Bill Dorrian Network Administrator Desk: 904-273

DRBD seems a suitable alternative, but I looked into it and it seemed quiet complex. I am mostly interrested in asynchronous replication, and I'm not sure if this works in a proper way. The proper way for me means that write order is preserved for consistency reasons (explained below), and I can't

BDsync: Block Device sync

2012-06-27 Thread Rolf Fokkens
Hi! After having wrestled with rsync and several patches I found a solution to synchronize block devices: BDsync. Bdsync can be used to synchronize block devices over a network. It generates a "binary diff" in an efficient way by comparing MD5 checksums of 32k blocks of block devices. This binar
