Almost a year after releasing Retrospect 8 for the Macintosh, EMC Retrospect (formerly Dantz) have released the Mac Retrospect 8 User Manual.
EMC have announced that they have released version 8.1.148 of Retrospect, which supports using PowerPC based computers as the backup server.
EMC have after three years finally released another version of Retrospect, Retrospect 8.0 for the Mac (well, Intel ones at least, PowerPC support is still forthcoming). Changes from version 6.1 are documented here, and here is a list for upgrade pricing
Notable changes include
- Support for up to 8 simultaneous tasks
- Wake on LAN support
- Delayed verification
- No FTP backups, yet
- AES-128 and AES-256 encryption support
- Staged backup “Disk to Disk to Tape”
- Fast catalog set rebuild (usually requiring only the last tape of the set)
- [Edit] No support for accessing archives created with Retrospect 6.1 or earlier (yet)
If you’re interested in making sure Retrospect 8 works for you, check out the Retrospect 8 beta downloads and comments in the forum, and make your own if you find something is broken!
A sobering tale from the operator of social bookmarking site ma.gnolia which lost half its users bookmarks through not having a decent backup. Interestingly they were running off 2 Xserves and 4 Mac minis.
- They had RAID (but of course that doesn’t protect you from data corruption, as both copies get corrupted).
- They did a FireWire backup (but of course that just backs up your corrupt database).
Hint: mysqldump is your friend.
Remember, sometimes the cloud blows away.
Interestingly the latest version of OpenSolaris (2008.11) includes a feature called “Time Slider”, which allows you to drag a slider to get to an older version of the file system state. I’m not sure if this leverages ZFS’s features or if it’s just hard-linked. Comments on the Javalobby site by Roman Strobl indicate:
Btw I believe what we have in OpenSolaris is better than time machine because a) you don’t need to use an external disk, b) the snapshots are immediate and don’t consume extra space other than differences from your current disk contents c) you don’t have to activate the backups, they happen automatically. So you also get more granular access to history. This is the first version of the feature so we plan to improve it in the next release.
I’m not sure that Time Machine’s going to prove much use to me if it spends longer than a weekend “Preparing backup”. Maybe if I left the machine backing up all week and only used it on weekends? Contemplating nuking the backup and starting from scratch as that way at least it’ll not have to do any comparison with the existing backup.
Meanwhile Spotlight is claiming that it’s 3% done indexing the backup volume and has 49 hours remaining. Sigh. I just added the backup volume to the list of things not to index (Why doesn’t that happen automatically?), and I got an error dialog. But re-opening the Spotlight preference pane shows the volume was added anyway. Now it’s still indexing it, but claims it’s 1% done and only got 3 hours remaining.
I’m thinking it’s time to fire up Superduper.
Check out these USB/eSATA/FireWire/FireWire 800 hard drive “Stage racks” also a similar gadget on Amazon.
Just as long as you don’t knock it over. Fortunately they include weights in the base. Unfortunately this increases the shipping cost!
So, the first Time Capsule backup over Gigabit Ethernet took about 8 hours to backup an 80 Gb drive. So, the 160Gb drive should take 16 hours? So far it’s Â been over 24 hours and we’re stuck at 132.07 of 145.81Gb (There are 2,007,881 files to back up!), Â and not Â moving. The weird thing is that MenuMeters shows around 600KB/s of outgoing traffic, presumably to the Time Capsule as everything else Â has Â been quit. At that transfer rate I’m estimating 8 hours left (time for Â bed!), but it’s hard to tell as the progress bar doesn’t seem to be moving. Edit- Something like 32-36 hours all up I think.
Picked up a 500Gb Time Capsule. Got home and was somewhat in a hurry. Power cable was a bit hard to get pushed in properly, although there was no visible evidence of why this would have been the case in either the plug or the socket.
Ignored the “Install this first” CDs, as usual, and fired up Airport Admin utility under Leopard on the wired LAN and it found the existing Airport Express. Did a “Save As…” to save the config of the existing Airport Express (including passwords). Then unplugged the Airport Express and plugged in the Time Capsule, attached to the network cable that used to be plugged into the airport express. Interestingly the assistant offered me the chance to use the Time Capsule to replace an existing wireless access point, but it wanted me to find it (and I’d just unplugged it :). So I plugged it back in to power and the LAN, but the Assistant couldn’t seem to find it. I gave up at this point, hit the Manual button and just imported the settings from the Airport Express (seemed like a safe bet) into the Time Capsule’s settings. This seemed to work. Changed security to WPA Personal and restarted the Time Capsule.
So, now turn on Time Machine on the Leopard box and get it started. That was at 18:30, and it’s now done 47.3 of 69.44Gb (1,396,130 items from my 80Gb drive) after some 5.75hrs (over Gigabit).
Meanwhile, every other machine had to have its Airport connection changed to WPA Personal, and even though I’m pretty sure I typed the password in several times, it took a while to register and stick (at least I hope it’s stuck now!).
Are network speeds faster? Hard to tell. I haven’t maxed out the speed as currently we need backward compatibility with 802.11g until the next round of upgrades. It offers 802.11n on 2.4 or 5GHz, and 802.11a compatibility as well as 802.11n/b/g.
Other noteworthy things are that the Airport Admin utility displays a set of warnings about the current Time Capsule configuration (ie no DNS, multiple DHCP, etc.).
The Time Capsule also offers to sync with a timeserver, and also flash its light if there’s a software update available. This is much less useful as it’s going to be stuck in a separate room where I’m unlikely to see its flashing light.
There’s also support to “Advertise configuration globally” via Bonjour, or so it seems to make it available globally over the internet. I don’t enable this.
I’d heard rumours of it running hot. Sure, it’s warm, but not really any warmer than my ADSL router, and it’s been doing a lot more work for the past 5 hours. Plus it’s got an internal power supply, so it’ll be warmer from that alone.
The other thing is now there’s an extra shared volume appearing in the Finder. Logging into it reveals a shared disk onto which I can put stuff. Cool. Checking in the Airport Admin shows it’s a guest read-writable volume, which is probably not good by default. Now locked down 🙂
So far, it seems to be behaving pretty much as expected. I could do setup in a hurry without too much pain. It claims to be backing up at a reasonable speed.
Now I just need to test recovery 🙂
