Thank you! Any more feedback? The more you tell us the more we can help. Can you help us improve? Resolved my issue. Clear instructions. Easy to follow. No jargon. Pictures helped. Didn't match my screen.
Incorrect instructions. Too technical. Not enough information. Not enough pictures. Any additional feedback? Submit feedback. The files are not compressible so I won't be using compression. Yep - replicate does error checking during transfers, while rsync does not though it will check CRCs the next time, iff you use option -c and rscyncd on the Windows end.
And I was trying to figure out if rsync had any kind of error correction for the exact reason you just explained. Now I'm wondering if I should do 2 rsyncs to send the data to the server. Once to get the data there and a second to do the CRC check. I know someone that migrated a server a few years ago using FTP. That didn't go too well for him :P.
Thus the mention of the second rsync! JaimieV said:. Click to expand That initial phase will take as long as it means to re-read the files at each end, a few hours probably. If you're really lucky the rsyncd might cache them long enough to do the second pass straight afterwards, but don't count on it. Note that if you don't have an rsyncd at the remote end ie you mount the SMB share and treat it as a local copy operation but using rsync , I think that means you can't do the CRC comparisons at all.
Well, I'm going to try to go with rsync and do it twice so it verifies the files are good. Also I will look into doing replication for the return trip if only so we can get a good comparison for which is faster: rsync twice or replication. Last time I tried to use replication I couldn't get it to work quite right. But when it didn't work I didn't mess with it any further since I was on 2 VMs and wasn't sure if that was related. So I'll reply back in weeks when all of the data is moved with info on how it all went.
Best of luck! Joined Oct 30, Messages Would it be possible to install all the hardrives into your final machine, install freenas, mount your old raid configuration as an NTFS volume in freenas and copy everything localy, from ntfs to the temporally zfs. After you have copied all the data from the ntfs volumes, you can convert the drives erase, format and create to the definitive zfs pool and copy everything back.
That's the way I did the migration. There aren't enough hard drive bays on the server to add 10 more hard drives nor enough SATA ports. It's just not really an option : Trust me, I wish it were. Well, so far this is looking like a much worse nightmare than I had thought.
It started without a hitch So it looks like rsync is a very bad choice for an initial transfer if speed is a concern. Replication obviously isn't an option at the moment since I still have data on the Windows machine. Come to think of it.. Edit: Compression is disabled already :. Whatever is going on, rsync. I did let it do about 50GB and then did a second sync. It took only ms to complete so clearly rsync works on a list of checksums as it goes which could explain the CPU usage needed.
Doesn't CIFS have its own checksums and such to prevent corruption? Perhaps do a CIFS transfer then run an rsync over the top after? Or if you're not pressed for time right away try other rsync servers on the Windows side. I've not used Deltasync and its results seem pretty rubbish. From the web interface, users will be able to see how much space a given snapshots take up on the volume and delete, clone or roll back to individual snapshots as needed. ZFS snapshots can be used as local backups: they can also be used to create remote backups, being much more streamlined and smaller.
Replicating snapshots of the local filesystem on a remote ZFS file system will create a complete duplicate in a remote storage, allowing you to relocate the data. In addition, additional snapshots of the same filesystem can be sent incrementally, reducing the size of each backup to changes made between snapshots only. In case of catastrophic damage to a local ZFS file system, any backup snapshot can be sent to a new ZFS file system, recovering all data until the last backup.
Encrypted volumes can only be read by FreeNAS systems that have the master key for that volume. The user will be able to create a passphrase that will allow him to add extra protection to his system against loss or theft. It will allow us to obtain compliances on the GDPR legislation. Another reason to use cryptography is that it will allow the protection of confidentiality even during the discontinuation phase of the hard disks since the units will no longer have to be deleted as they are already encrypted.
