GoodSync allows users to back up files to external cloud services, and the list of third-party cloud options is extensive, and includes Google Drive and OneDrive. We can confirm all automated updates were accurate and remained on schedule. We were also able to program automated daily and weekly backups. We programmed GoodSync to update all edited files automatically, eliminating the time it takes to do manual updates. This feature is ideal for anyone managing large numbers of files on their system.īeing able to transfer data in real-time made our workflow much more fluid. Having the ability to transfer portions of data rather than full files means GoodSync provides shorter backup times and better performance. What it does offer, however, is reliable and well executed.īlock level data transfer is often lacking in similar services. GoodSync isn't a feature-stacked service. I also believe MD5 is not used by B2, but SHA1 (i.e.GoodSync offers a range of features commonly included in this type of service (Image credit: GoodSync) Now that said, this is not the direction I really waned to check - I really wanted to modify the data on the cloud, but I was unable to figure out how to do so without changing dates.īut back to the SQLite table - I have browsed through all the tables there, and may have missed it - but where in there is any kind of checksum stored for B2 against which do this check? I did a consistency check, and it passed, so there was no MD5 check against the original file. I backed up one file to B2, and then modified the original on disk without changing the modify date. There is also a "differential parts" table which has checksum data, but it contains no rows for the destination type of B2, which is what I was testing at the time. I have backups in there for both S3 and B2 clouds. The "cloud_versions" table contains an "md5" column, but it is null for all rows. I decided to browse the data in the SQLite database. Thanks again, and I hope you do not mind if I persist a bit. Since some cloud services (including Amazon I think in all) calculate and provide on request an MD5 checksum - without needing to read the entire file - this can be more efficient than it may sound, though multipart backups obviously present an issue.Ĭomparison with S3 explorer won't apply except for very simple backups, as file structure, encryption, incremental parts all get in the way.ĭo these options in some combination provide a mechanism for verifying that the source and target of a backup actually contain the same data - not just the same list of files (if indeed that is all Consistency Check does)?ĪNd even if "no" to the above, what does the MD5 option in Connections actually do? If I look at a product like Goodsync, I can enable MD5 comparisons and it will do a separate MD5 verification after write, and there is also an option to compare bodies on demand if desired. In the Cloudberry Explorer, there as a compare option which is documented as using MD5 to compare files, but I can find no similar feature in Backup. There is no real documentation on it that I can find, and on the old forums the question "what does it do" went un-answered. not specific to a cloud provider or backup plan), there is a "Use MD5 Checksum" Under the Connection options tab for programs (i.e. There is no indication that it checks file contents to see if they are in fact the same. Emphasis on "seem" as details for many options is sparse. Web postings at the time it came out seem to indicate it compares file existence, not contents. Especially with a problematic service such as Amazon Cloud Drive, but really for any backup it is useful to check whether the backup is correct.Ĭloudberry Backup has a consistency check, which reconciles the local and cloud copies.
