A heavy burden on the soul is the fact that even though I'm already doing backups — not doing it properly.


The data on the computer divided into two groups: big and bad (the films, the image of the installation disks, etc), a small and important (documents, scripts, source code, etc). Fortunately, photography and video are not engaged so large and important files there.


At this point an important directory once a day are copied automatically using rdiff-backup to another hard disk partition. Occasionally (so as to automate this fails) the contents of archived section moves on DVD.


An obvious disadvantage: copying to an external medium rare (a couple times a year), and up to another hard drive partition will not help in case of problems with the disk.


The size of the important data, about 8 GB, usedonmost changes infrequently.


The right product (or combination of products), which would have the following properties:

  1. Automation — not required human involvement while copying
  2. Incrementalcost — copy only changed files, and even better, only the changes in files. With some babouta larger period to do a full backup, just in case. UPD: to store not only the latest version, but (differential) all previous (as does rdiff-backup)
  3. Save backups in the cloud. External media are not suitable due to the lack of automation possibilities.
  4. Encryption on the client side. On the server side should not be stored anything meaningful. The encryption key must be only on the client, and (backup) on a durable medium, but not on the server.
  5. Control. When copying, the human part should not be required, but it is necessary that in case of malfunctions it became known. For example to display the report results (success/fail, time, size) copy once a week.
  6. The opportunity to work under Windows
  7. The ability to work in "notebook" terms (the Internet is often, but not always. The laptop is included not always. When using battery power — postpone/pause)



The first thing comes to mind nnCron + rdiff-backup + TrueCrypt + Dropbox, will describe the disadvantages of such combination.
  • Synchronization will occur only when you unmount the tc container. So you have to mount/unmount script container every time
  • The restriction on the length of the path in some of the API, which rdiff-backup crashes for some files
  • Some files can exclusive be opened in other programs, which leads to problems when copying
  • Copying is not atomic, so some files may be're discordant (though it rarely gives a problem)
  • There is no error control. One day something may go wrong and I'll never hear about it



Plus: if you include a pack-rat, it is possible to replace rdiff-backup to any rsync (incrementalcost and the version history will provide Dropbox) to save space. Although there was (or is?) ways to view in Dropbox any directory and all files in it as at some point in time without restoring a single file. And with the active use of such features, it does not consider whether this abuse = ban.

UPD

Found an article comparing the services: Backup online, yet tend to CrashPlan

UPD2

Eventually settled on Duplicati + S3, support all of the above but quite a lot.

For other OS alternatives (or rather the original version) is the duplicity, from the author of rdiff-backup.

Inbox today to promote a similar service (just launched), encrypting them, etc., but damn, even more out of dropbox.

Mozy Home: $5/month, unlimited space (I have 80GB).
Backup by schedule, incremental, in the cloud. Previous versions of files are kept for 30 days.
Before sending, you can encrypt your with 256-bit AES key. After each backup shows a window with the status (how many files are stored, how long it took, how long ago was the last successful backup). Status and process. If the problem happened immediately lets you know.
Battery operation does not recognize, but you can manually pause it. Works under Windows and Mac OS, download all files through the client and through a web interface.
Can simultaneously back up in the cloud and on local storage.
For tests give 2 GB for free.
\r
P. S. If appropriate — can give a referral link :)

IMHO in your case is enough Cobian Backup + Dropbox
Cobian Backup can create incremental backups and put them in encrypted 7z archives, but when connecting to the Internet — dropbox, the case will be to store yourself.
Cobian Backup is able almost everything that is required: incremental backup, encryption, archives, work schedule, showing/sending mail magazine. Not only is it possible to restrict the execution of the task if the laptop works from the battery.

If You are considering not only a free solution, you can also look at the Acronis Online Backup. Almost all (about working in "laptop conditions" I do not know) the above can.

colleagues, and whether that could go directly to the cloud pouring without local backup copy. I.e. the ever-popular clouds (dropbox/GDrive/andreiv) disappear because keep a copy locally!
Ideally you want AT which chose what/when bekapit, ukazyvaesh, credence to the cloud and it bekapit directly to the cloud!

burdakovd not prompt? Duplicati now, too, but faced with the fact that this program can not work in service mode, the settings (the scheduler) it is impossible to set a schedule the schedule the task more than once a day, and the tray icon is in the way...

I want to put this program on a production server, but these flaws stop you.

Under all claims of the author of a topic, is probably the most suitable Russian development - utility backup Exiland Backup (Standard or Professional). And encrypts and backup to the cloud (currently only Yandex.Drive, DropBox and others in their plans). On Yandex.Disc, by the way, give free 10 GB.
Encryption. Fault tolerance if the connection breaks (uploading), copying speed is relatively high (achieved optimal algorithms and a lot of threading). A notification on a mobile phone or e-mail in case of problems with creating a backup. There is even they have an article about backups on Yandex.Disk
