yes - from my point of view they are file servers, but you are right: they are BackupPC clients. Also one information ahead: The system I talked about was a BackupPC-3.3.1. > When you said "on my BackupPC I deleted "A:data"" did you mean you simply > removed that share from the config.pl for server A, or did you actually > delete files below the BackupPC store (eg, > /data/BackupPC/pc/serverA/NNN/fdata)? I deleted the share from the config.pl. My intention was to migrate the share from one "client" to another keeping it's backup history. I have not removed any files expilicitely. > If it was just a config change, then all the old backups of the data share > on server A should still be present (until they otherwise expire based on > the config settings). During nightly cleanup BackupPC started removal of the "deleted" share of client A. Unfortunately I noticed this after about 20 hours of removal (I have an amount of about 4 million files at about 30 snapshots, lasting about 5 years back). I understand that if a share is deleted (from config.pl), BackupPC assumes that the share is not needed any more and thus starts removal. Actually it started to remove hard links from the snap shots. Many of them are empty now and I am afraid that the pooled files also have been deleted, because their hard link counter has decremented to 1. Anyway I am afraid that I would not be able to reestablish the removed links. So my question is, how can I tell BackupPC to "move" a share (including it's history) from one client to another? Meanwhile I noticed your release of Version 4 and I did a complete new setup. My hope would be that in case of damage there would be at least a chance to recover files from my old V3-Backup. I kept it and mounted the volume read only, because BackupPCv3 insists in doing cleanup as soon as I start it on I writeble volume. So my other question was, how to disable cleanup. The last question in this story then is how to merge another backup into the "clean-upped" one. I found that this question was discussed several times but it seems to be complicated. After all I want to state, that I am very excited about your project. I have used it for many years now and it has helped in many cases of file damage or loss. Also your project is a prime example of very good software design.
