MySQL backups with EBS snapshots. Assaf Arkin’s 45 line ruby script shows how to lock tables / XFS freeze / create an EBS snapshot / unfreeze and unlock, with hourly snapshots preserved for the past 24 hours and daily snapshots for the past week. Is an EBS snapshot enough to restore your data to somewhere other than EC2 though? # 13th October 2009, 12:34 pm


There. Is. No. Long-Term. Data. Storage. Solution. There is only a series of short-term solutions punctuated by data migration from one medium to the next.

Making Time Machine work with the ReadyNAS. Finally, a decent set of instructions on using a ReadyNAS with Time Machine. The trick is to create a local sparse disk image with a magic name (based on hostname and eth0 MAC address), then move it to the NAS. # 4th May 2008, 5:55 pm

Amazon takes EC2 to the next level with persistent storage volumes. You can store a snapshot of a storage volume to S3 with a single API call, making backups trivial. # 14th April 2008, 8:04 am

iTimeMachine. Enables Time Machine to see network drives (a ReadyNAS NV+ for example). There’s also a defaults setting but it didn’t seem to work; this did. # 29th January 2008, 11:33 pm
