Hi,

I have 2 servers primary and backup which rsync every night. Couple of days back my primary server failed and we started using backup server as the main. There was no rsync between the primary and backup during the down time of primary server.

Now the primary server is fixed and is back online with the data up to the time we stopped using it. Since backup server now has more updated data can I safely run rsync for once to copy data from backup to primary server? Once primary and backup have same data then I will start using rsync again from primary to backup.

Theoretically this should work but I am putting out this in case anyone can point out any step I should be careful about.

Any suggestions is much appreciated.

Thanks,
Mayank

You should take both servers offline and prevent any users/applications from accessing both machines while you transfer the data back to primary.

Yep, rsync will run Fri/Sat at 1am.


Thanks for the reply.

Since your primary server was down and during the downtime of primary server, backup server acted as primary server and now your backup server has latest updated data. Now you can surely copy data from backup to primary server.

just run same rsync form backup server to copy into primary server.nothing to worry .just take care that do this in offline mode.or when user pc is not in use.its better one.

Thanks everyone for the responses. The same rsync scripts worked just had to change the paths.
