Oh yes you taught me that trick for running the script checking and restarting mirror-stream process.

I can then snapshot it Daily and Share the Snapshot Links Directory using another Samba Share. Suppose I configure the prune-min period of the Slave pfs as 2d. Will I be able to generate 5 min snapshots from it of the previous day from it should I lose the Master PFS Disk? I mean if you have the history retained for 2 days can you create snapshots of the filesystem of a previous time? > :I might get rid of backuppc if I can store at least 2 years worth of > :Daily backups like this. > > You always want a backup on some other machine somewhere, no matter > what. > OK then :-) > :Is there any way to find the space used by a single PFS and the space > :used by its snapshots ? > > No, someone would have to write a feature in the hammer utility to > calculate it. > > Alright Thanks :-)
