![]() I just insert the usb hdd to my PC sometimes to get my files directly to the pc, since this is convenient for me. ![]() After completing the syncing I just remove the usb hdd and go to sleep! I do this not every night, but I do this when I think some important data has been uploaded to the nas or some nas documents have been modified. In my case, I just sync a nas folder (.Qsync folder!) manually to a USB hard disk with HBS3. a ransomware or virus attack won't result in a total meltdown. and keeping the backup medium offline when not needed + manually controlling when to run each job is enough for me to get some sleep at night not worrying much. that's 2 duplicates of my data, in plain sight without qudedup. I now have one 1-way Sync job, and one Backup job (with the option 'remove files from destination' disabled). i rarely have situations where i wished i hadn't deleted something on the NAS in the first place, in case i do i now have versioning to fall back on. so i anticipated that 5 versions backward for those files would be good insurance. the remainder is mostly static and doesn't change much. I'd say 5% (in terms of total data stored) is replaced with new files of the same name. most of it rarely changes, a small chunk of my NAS is updated daily with files coming from computers in the LAN. ![]() I think for my needs, where the destination is not a NAS and is not a QNAP product, going with Backup + 5 versions of my data is fine. I dislike proprietary backup formats so this is what I have done with every version of HBS. If you disable QuDedup the backup will instead be plain files in a plain file system, the same as a sync but with the added benefit of versioning. I went to File Station in my backup NAS and based on the time and date of each backup generation I could easily go back 10 days to downlad the older version.ĭon't know much about deduplication or how that works in this case and don't know if it's a benefit to me for what i'm doing.Deduplication is useful if you store the same data in many different places in the file system.īackup deduplication, known as QuDedup in HBS3, however also come with a Qnap-proprietary backup format. Last night I realized that I needed an older version of a document that I had changed a week ago. On a data set with 3.88 TB that 34-generation backup use up a little over 5 TB in the backup unit. That may be overdoing it a bit as I have the possibility for that right now but it's good as an example of what's possible. There I have 34 different generations of backups stored stretching as far back as 12 months. So thats a big no for me.And by that you miss the the absolute most valuable feature that HBS3 offer - the versioned backups that are very storage efficient as only changed and deleted files use up storage in the older generations.Īs an example I do nightly scheduled backups to my off-site backup NAS. One reason i don't use the backup, but instead i use one way sync (rsync/rtrr), is because when i try to use the backup, it creates a root folder whether u want it or not (it has a name and a date if i'm not mistaken). Asking Qnap will give you the best answer and that is also the best place to file your feature request. I don't know if there's a technical reason for the decision or if it's just they didn't figure it necessary for plain file systems when there are other means available. The only option to verify a backup would be to first do a restore and than compare the source with that. Both push and pull operation is available and even two-way syncs to other Qnaps.ĭata Integrity Check is only available when the proprietary HBS3 backup format is used and without that it wouldn't possible at all. In communcation with other servers you're free to choose between the protocols RTRR (Qnap only), Rsync, CIFS/SMB and FTP. Synchronizations always only create normal files in plain file systems. Backup only support push operations, never pull. Backup jobs to non-Qnap servers aren't possible and the Qnap-Qnap backup protocol used is always RTRR. You also have the option of using a HBS3 proprietary backup format (for deduplication and encryption that is a requirement) or a plain file system backup. Backups offer several different options like deduplication, server-side encryption and storage-efficient versioning (different backup generations).
