replication failed file is corrupted

Thread solved

I am unable to replicate to the cloud. I receive

             Replication failed. The file is corrupted.

I don't know if it's related but this started after Acronis support had me install the latest update (in a vain attempt to resolve a cloning issue since solved in Community). The local backup appears ok. It is green and I performed a successful restores of some files as a test. I just cannot replicate or validate. I assume validation fails due to the replica . What are my options? Can I avoid deleting the entire replica? Replicating to Acronis Cloud is extremely slow. The first full replica I created took somewhere between 36 and 48 hours.

Thanks in advance for your help

Benjamin, I can only suggest that you delete the failed replication and forget about using this feature and setup a separate new backup task for the same source data to backup directly to the Acronis Cloud instead.

Replication to the Cloud, in my opinion, is flawed unless you have a really fast & reliable broadband connection to keep the volumes of data to reasonable upload times and be able to cope with following the backup scheme for a local backup with regular Full backup uploads etc!

Doing a direct backup to the cloud has obvious benefits over using replication.

Both have to do an initial Full backup upload - replication will start over again if that fails - direct cloud backups will tolerate interruptions etc and will resume.

Direct cloud backups only ever do a single Full upload, then use a Delta hybrid incremental backup scheme to identify and only upload changed blocks of data, plus use versioning etc, so perform faster & better on subsequent runs.

Replication might be more useful for regular users if it was enabled to local destinations such as a NAS etc, but that isn't an option at this time!

Thanks. I do have good internet but not worth risk if it corrupts.

Question on versions, once a full and it's five incrementals complete, a new full is created. Is the metadata of Full #2 linked to Full #1 (and it's incrementals)? If not, they should have allowed you to selectively validate though validating latest was step in right direction.

Yes, metadata links the different backup chains so these are no longer independent of each other!

You should be able to validate each chain separately via the changes made for validation in ATI 2021.

This is what I currently have for my single backup job

Full 1

Incremental 1.1

Incremental 1.2

Inc. 1.3

Inc. 1.4

Inc 1.5

Full 2

Inc 2.1

Inc 2.2

Inc 2.3

What does it define as "latest version"? The last link in the chain, in this case incremental 2.3, or the last full version, Full 2?
i'd like to get back to a useable validated back up and replica. Then, create two new backup jobs, one local and one cloud. What is the best approach? As I see it, I can

1. delete replicas back to a certain point, validate, and replicate

2. Delete all replicas, validate, and replicate

3. delete both local and replicas back to a certain point, validate, backup and replicate

Benjamin, is this a files & folders backup using the older .tib file structure & naming, i.e. with separate incremental files using _inc_b1_s2_v1 names?

Personally, I would just delete the corrupt replica and leave the local files intact, then create a new Cloud backup task to replace the replica, assuming you have sufficient free cloud storage without needing to delete any other replica files still stored there.

With regard to the validate option, my understanding of 'latest version' would be all your backup 2 files.  It doesn't really make a lot of sense to only validate a single incremental file on its own as it is totally dependent on the previous files for that chain.
See the ATI 2021 User Guide explanation of the validation options where another term is used for validating individual backup 'slices' - Validate the latest diverse backup only - A quick validation of the last backup slice.  This available via the Options > Advanced setting panel.

it's the new combined tibx. I'll follow your advice. As always, great help. Thanks so much! Without you and your fellow community MVPs, I would have to switch to another product.
