It keeps old files until the backup containing them gets expired by
newer backups.



My experience with Windows and reinstalling the OS is that many files 
change during a reinstall (notably, almost all of the dot-net libraries 
will change) and the rsync client will need to read them all, but 
there's usually between a 70-90% match (assuming the same version of 
Windows.)

I am using rsync as the transfer method.

Which transfer method are you using? With rsync or rsyncd, the data will not be 
copied again.

has about 5 terabytes of space available of which 3.7 terabytes is already 
filled with backups from the old Windows client and thus if it re-copies the 
data from the reinstalled Windows client (even if it later de-duplicates  the

Thanks in advance.

[BackupPC-users] Are Files Re-Copied In Pool On Reinstall of Backup Client Operating System

2018-06-19 Thread Akibu Flash 
I am using BackupPC 4 on an ArchLinux distribution to backup a Windows client.  
The amount of data on the Windows client being backed up is about 3.7 terabytes 
in the BackupPC pool.  I would like to reinstall the operating system on my 
Windows computer and would like to know the following:

1) Once I reinstall the operating system and direct BackupPC to resume backing 
up that Windows client, will BackupPC re-copy all of the data from the Windows 
client into the pool?

2) On resuming backing up the Windows client, will BackupPC basically first 
look at the data to be backed up on the Windows client and then realize that it 
already has that data in the pool and therefore will not re-copy the data but 
will link to it in the pool.

The reason I ask re re-copying the data is because the ArchLinux server only 
has about 5 terabytes of space available of which 3.7 terabytes is already 
filled with backups from the old Windows client and thus if it re-copies the 
data from the reinstalled Windows client (even if it later de-duplicates  the
