Topicbox-Message-UUID: 85c1b63c-ead6-11e9-9d60-3106f5b1d025 I use vac -a to back up several unix systems to my main Plan 9 file server. C= urrently I'm doing two nightly via cron and two sporadically (laptops); ther= e have been more of each in the past. In addition to storing the scores loca= lly, I wrote a little rc script that lives in /rc/bin/service.auth and accep= ts scores and stores them on my CPU server. Combined with a simple 9fs addit= ion, I can always "9fs foo.vac" and get foo's history of archives from all m= y plan9 systems. I've also done restores from p9p, but have not exercised th= at well. I considered using vbackup instead of vac on the unix side, but it d= idn't look practical to get at the results from plan9. Also, I really needed= to be selective in what I saad backing up (there's a few hundred Gb of post= -processed video I don't need to store on one of these systems, and growing d= aily). This has worked very well for me overall; my only problem has been vtcache e= xhaustion on some backups, which I haven't been able to track down. Thankful= ly the error is on backup, not restore, so you know something's gone wrong w= hen it happens. My message about vtcache is at http://9fans.net/archive/2010/02/307. I'm not= sure I pushed the absolute latest to sources, but some version of my unix b= ackup script is at /n/sources/contrib/anothy/bin/rc/vacbak.=
