[Nssbackup-team] [Bug 1000171] Re: sbackup-upgrade-backups incredibly slow

[Jean-Peer Lorenz]

Hello Francesco,

thank you for using sbackup and reporting this issue!

You are absolutely right! Performance of the upgrading process is a
total nightmare and, also, touching existing snapshots is a BAD idea.
Therefore, upgrading is highly not recommended.

I am working on making the restore backwards compatible and there is
basic support for reading and writing arbitrary snapshot versions in my
current development branch. Unfortunately, I'm short on time and cannot
tell any release date when this will be finished. Help is highly
appreciated.

Thank you for your help and sorry for any inconvenience!

Best regards,
Jean-Peer

For me:
19:29:56,066 - INFO: Creating the SNAR file

Right now (19:46:33) file size is: 392766 bytes

I have a locally connected USB 2.0 drive...


As I already noted in 1000896 - when you are in need of restoring a snapshot 
you usually don't have several days time to do that. 

First having to convert the snapshot before being able to apply it - and
risking the integrity of the very backup itself when doing that - is
really not user friendly.
